Geneva, Switzerland, February 28, 2024 STMicroelectronics SRK1004 synchronous-rectifier controller eases the design and enhances the efficiency of converters built with silicon or GaN transistors, including industrial power supplies, portable-device chargers, and AC/DC adapters.

Capable of withstanding up to 190V at its sense input, the SRK1004 can be connected in a high-side or low-side configuration. Four variants let users avoid complex calculations by optimizing their design through device selection alone, selecting gate-drive voltage between 5.5V or 9V, with logic-level MOSFETs, standard MOSFETs, or GaN transistors. Suitable for noncomplementary active clamp, resonant, and quasi-resonant (QR) flyback topologies, the SRK1004 introduces a next-generation turn-off algorithm that simplifies operation and saves energy.

The features of this controller enable converters to provide a high output power rating within compact dimensions. The operating frequency can be up to 500kHz, allowing the use of small magnetic components as well as maximizing the benefits of wide-bandgap technology when using GaN transistors. The controller is fabricated in STs silicon-on-insulator (SOI) process, which ensures robust performance while permitting a tiny 2mm x 2mm DFN-6L package.

By operating with a supply voltage from 4V to 36V, the SRK1004 can be powered from a variety of standard industrial bus voltages. The wide input-voltage range also provides flexibility to adjust the step-down ratio for optimum efficiency. Also, with fast-acting short-circuit detection built-in, the controller helps build rugged and reliable equipment.

Of the four variants introduced, the SRK1004A and SRK1004B are configured for 5.5V gate-drive voltage and can be used with logic-level MOSFETs or GaN transistors. The SRK1004C and SRK1004D for 9V gate-drive voltage are suited to MOSFETs designed for standard gate-drive signals.

All variants of the SRK1004x synchronous rectification controllers are in production now and available from $0.45 for orders of 1000 units. The evaluation boards, EVLSRK1004A, EVLSRK1004B, EVLSRK1004C, and EVLSRK1004D, are also available to accelerate evaluation and design start with each type, at the budgetary price of $50.00.

ICDM Survey Reveals Imperative for Boards in ASEAN to Realign Priorities Towards More Effective and Sustainable Governance

KUALA LUMPUR, Feb 23, 2024 – (ACN Newswire) – The Institute of Corporate Directors Malaysia (“ICDM”) recently concluded a comprehensive survey across Southeast Asia in collaboration with its eight (8) partners under the ASEAN IOD Network that highlights the imperative for boards to sharpen their foresight to assess and steer their organisation’s business model, governance, talent, dynamics, and culture as they position their boards for the future.

The survey of 335 respondents comprising boards and C-Suites management from across the region reiterates the urgency for boards to evaluate their effectiveness and shift their current strategic board priorities to ensure they address the key threats that they expect to be more prominent over the next two (2) years. The four (4) key threats include:

(i) Having the right talent and leadership;
(ii) Diplomacy in managing macro and geopolitical uncertainties;
(iii) Sustainable and effective operational strategy;
(iv) Board-management relationship and dynamics.

Michele Kythe Lim, President and Chief Executive Officer (“CEO”) of ICDM emphasised, “Amidst the ongoing economic challenges, we remain steadfast in our commitment to navigating leadership in the dynamic landscape of Southeast Asia. Governance is coming into focus on a more profound level in the wake of heightened stakeholders’ expectations, as evidenced by the many changes taking place on boards around us recently. As leaders, we recognise the pivotal role of talent, the power of effective leadership and the imperative of sustainability in our current environment and that a paradigm shift at the board level is necessary to confront the reality and barriers in their pursuit for growth. This regional survey is part of our hope to collectively transform leadership and drive businesses to greater heights by encouraging them to launch into action and openly address the critical areas in board and corporate governance that will nurture deeper cohesion in organisations.”

Urging boards to cultivate a forward-looking mindset and ingrain a more robust culture to turn risks into growth opportunity, ICDM’s 2024 ASEAN Board Trends Survey identified five (5) critical areas in board governance that require immediate intervention to reinforce board effectiveness and ensure companies are equipped for the challenges of the future. These include:

(i) To Realign Board Agenda and Set Priorities Right: Boards often cling to outdated approaches, looking at things through yesterday’s lens and failing to adapt to changing circumstances. As a result, corporate priorities overlook the key threats and changing environments. Boards must stay informed about current and future business trends while adapting to new threats, risks and opportunities that build their path to the future.

(ii) To Improve Board-Management Relationship and Dynamics: Misaligned priorities between boards and their management were noted throughout the survey, with differing ideas on key organisational priorities and areas that require more attention from the board. While boards place greater importance on business model agility, diversification and transformation, management believe human capital strategy and development should be a priority. Boards and management must conduct more meaningful discussions, realign and agree on priorities as well as expectations of both parties to enhance the working relationship dynamics for increased effectiveness.

(iii) Progressive and Forward-looking Board Architecture and Culture: Management express reservations about the board’s current ability and skillset to steer the company strategically. The existing blend of knowledge, experience, and qualities fall short of supporting evolving business needs in the coming years. Boards must begin cultivating a culture of open dialogue, courage, and candour amongst each other. Nomination and Remuneration Committees (NRC) play a vital role in ensuring the right mix of board members, led by the chairman who plays a pivotal role in fostering a progressive board culture and managing board-management dynamics. 

(iv) Board Effectiveness at Taking Stock: While boards may perceive their performance positively, management highlight a lack of diverse perspectives which hinders insightful discussions and creates blind spots to critical issues. Some respondents felt that their board deliberations do not bring value or enhance decision-making quality, with over half stating that board members rarely express conflicting views. Boards must look internally to assess their value proposition, skills, governance and mindset to effectively catalyse their growth.

(v) Navigating Board Sustainability Challenges: While many acknowledge that sustainability goes beyond mere reporting and some boards are already embracing or planning to adopt sustainable strategies, management remain sceptical about the board’s current knowledge and ability to fulfill its oversight role. While boards recognise that their challenge lies in setting up the right governance with clear performance target measurement, they must also acknowledge the important need to support the human capital function and concerns through talent governance. Health, safety and wellbeing, talent management and succession planning are among top sustainability matters for boards’ attention.

As boards begin to address these critical areas in governance, the key actions they need to take begin with undertaking a formal board effectiveness evaluation encompassing candid, 360-degree assessment. Boards must obtain holistic perspectives to better understand their current landscape, working dynamics amongst themselves and between their management, as well as identify development needs. It is vital that boards reevaluate their composition and remuneration packages at regular intervals and proactively foster strong board-management relationships and dynamics. In realigning organisational priorities through joint strategic planning sessions, boards must practice the art of asking challenging questions for more robust discussions. Organisations must prioritise talent governance and organisational culture to ensure a conducive environment for innovation and productivity, while embracing sustainability agendas authentically, avoiding greenwashing, and embodying authenticity and purpose as leaders are essential for driving organisational success.

In addition to the 2024 ASEAN Board Trends report, ICDM also announced the formation of an ASEAN Directors Registry under the ASEAN IOD Network initiative. Aiming to go fully operational in July, the registry marks a significant stride in fostering global recognition for ASEAN board talent. Recognising the needs of boards with regional perspectives, this initiative aims to actively advocate for enhanced ASEAN representation on the boards of businesses with a presence in the region. With this registry, it seeks to elevate the value proposition for members of ASEAN Institutes of Directors by expanding their access to a broader spectrum of directorship opportunities and give organisations a wider selection of board-ready candidates with international or regional experience.

The survey was conducted in collaboration with partners under the ASEAN IOD Network, which was initiated in 2020 to better serve the board community in the region and beyond. These partners include the Institute of Directors Thailand (IoD Thai), Institute of Corporate Directors, Philippines (ICDPh), Vietnam Institute of Directors (VIOD), Myanmar Institute of Directors (MIoD), Singapore Institute of Directors (SID), Indonesian Institute of Corporate Directors (IICD), Darussalam Assets Sdn Bhd and the International Business Chamber of Cambodia (IBC). The survey can be accessed on ICDM’s website.

New Research Reveals Education’s Potential in Reducing Violence and Advancing Peace

The Global Partnership for Education (GPE), and the Institute for Economics & Peace (IEP), have released new research providing compelling evidence of the strong relationship between education and peace. Released on the International Day of Education, the analysis demonstrates how improvements in education levels are closely linked to more peaceful societies.

The past decade has been marked by lethal conflicts, crises and wars. Across the globe, wars keep taking countless lives, displacing civilians from their homes and leaving many more in a dire need of life-saving assistance. There is an urgent need to rebuild the foundations that can underpin lasting peace, and yet too often one of the most crucial of these, education, is often relegated to a development afterthought.

“This year began with a dismal global outlook for peace, but we can restore hope by urgently investing more in education,” said Laura Frigenti, GPE Chief Executive Officer. “It is time we heeded the mounting evidence that education is a smart, mutually sustaining investment in prosperity and peace.”

While the disastrous impacts of conflict on education are widely acknowledged, research on the reciprocal relationship between peace and education has been sparse and outdated. To fill this essential knowledge gap and provide evidence to drive sound policies, the GPE has partnered with the IEP to break down and better understand the relationship between education and peace.

Key finding: Countries with higher primary school completion rates are in general more peaceful. Conversely, countries that enjoy high levels of peacefulness have secondary school completion rates of 99 percent. On the other hand, countries that suffer from low levels of peacefulness have on average secondary school completion rates of only 52 percent.

Countries with high education levels enjoy more overall social and political stability, and the opposite is also true: countries with low education levels tend to experience a higher occurrence and intensity of internal conflict. In other words, better performance in education can reduce the severity and duration of societal violence and save lives.

Improvements in peace indicators see more investment in education. Countries that invest more in education enjoy higher levels of peacefulness. For example, in 2020, Namibia, one of the most peaceful countries in Africa, had the sixth-highest rate of government investment in education globally as a percentage of GDP.

Mounting evidence has shown that investing in education is essential for peacebuilding. There is an urgent need to ensure adequate resources are channeled to education. This can allow governments, donors and international organizations to live up to their collective responsibility of giving every girl and boy the opportunity to get the knowledge and skills they need to usher in a more peaceful and prosperous future.

New Study Reveals Evidence of an Ice-Rich Layered Deposit on Mars

New Paper Published by Smithsonian Scientist Tom Watters

WEBWIRE

Findings from a recently published paper led by Smithsonian senior scientist emeritus Thomas R. Watters reveal evidence that the deposits of the vast Medusae Fossae Formation (MFF) may contain a significant volume of water ice. The paper, Evidence of Ice-Rich Layered Deposits in the Medusae Fossae Formation of Mars, published in the journal Geophysical Research Letters Jan. 18, presents new radar sounder data that show the similarity between the MFF deposits and the ice-rich polar layered deposits at the north and south poles of Mars. Modeling of the compaction behavior of proposed ice-free geologic materials shows that none of them can account for the inferred electrical properties of the MFF deposits without pore-filling ice.

Finding evidence of layering in all the major units of the MFF makes a compelling case that the deposits are similar to the ice-rich polar layered deposits, Watters said. An ice-rich MFF deposit has important implications for the paleoclimate of Mars and could be potentially of great value to future human exploration of Mars. The MFF deposits are located at the Martian equator along the boundary between the northern lowlands and the heavily cratered highlandsan ideal landing spot for spacecraft as the lower elevation provides more atmosphere to slow a spacecrafts decent.

The MFF deposits remain one of the most enigmatic and least understood geologic units on Mars. Data from the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument onboard European Space Agencys Mars Express spacecraft initially revealed that the electrical properties of the MFF deposits were very similar to ice-rich polar layered deposits. New MARSIS data shows that similarities go beyond the electrical properties. Detection of interior subsurface reflectors indicate the presence of pervasive layering like that found in both the North Polar Layered Deposits (NPLD) and the South Polar Layered Deposits (SPLD) that are known to be ice-rich.

The new MARSIS data also shows the MFF deposits reach a maximum thickness of 3.7 kilometers (about 2 miles)the maximum thickness of the SPLD. Compaction modeling of geologic materials proposed for the MFF deposits that include volcanic ash, windblown sediments and windblown rock dust shows that they cannot account for the inferred density and electrical properties of such a thick deposit.

Ice-rich MFF deposits, less a dry, insulating cover material possibly volcanic ash, represent a large reservoir of water in the equatorial zone of Mars. The estimated volume of water is up to 50% of that of the NPLD, much more than the total volume of water in the Great Lakes of North America. The volume of water is enough to cover the surface of Mars to a depth of about 1.5 to 3 meters (about 5 to 10 feet). The ice-rich MFF deposits were likely left at the Martian equator during periods of high obliquity when the present-day equator would have been much colder and the polar regions much warmer.

Watters is a senior scientist emeritus in the Center for Earth and Planetary Studies at the Smithsonians National Air and Space Museum and a member of the MARSIS science team.
