our members of the Board of Directors are elected at the PSMA Annual Meeting held every year, usually held during the APEC conference. Each Director serves a three-year term and is eligible to be reelected for one additional term. In this issue we would like to introduce you to Ada Cheng and Brian Zahnstecher.

Ada Cheng is a Technical Marketing Consultant with AdaClock since 2008. In addition, she partnered with Anagenesis, to research and publish the "Power Supply in a Package (PSiP) and Power Supply on a Chip (PwrSoC) technical market reports. She has been involved with the PSMA since 2002 and joined the PSMA Board of Directors in 2019 and in 2023. In 2026, she became the vice president of PSMA. Currently she is an active member of the Marketing, Energy Management, Industry-Education, and Reliability committees.

One of her biggest contributions was challenging the PSMA committees to support APEC in some tangible way such as creating and running industry sessions, producing professional education seminars, suggesting key speakers for plenary, etc. As a result, the amount of industry participation in APEC has grown, and the conference has flourished while many other technical conferences have not. Lately she is leading the mentorship program at APEC, championing the Global Energy Efficiency Award, and co-chairing the industry-education committee.

Furthermore, Ada was an invited member of the APEC conference committee from 2003 to 2015 primarily as the OEM Initiative Chair which developed the Industry Sessions.

Previously Ada was a corporate marketing manager at International Rectifier (now Infineon), a market analyst at Gartner Dataquest for analog ICs, and held various electrical engineering roles at Motorola Semiconductor Products Sector (now NXP Semiconductors and ON Semiconductors). Ada received her MBA from Arizona State University and her BSEE from Carnegie Mellon.
