Abstract:
The need for an efficient power management solution has never been more critical across virtually all electronic devices and systems from low power to high power, smartphones to data centers, battery-powered components to renewable-energy-powered grids, and from stationary systems to aircraft. Particularly for ultra-low power systems such as untethered sensors and IoT systems, the key challenge is to maintain high delivery efficiency while satisfying increasingly demanding input/output requirements, space constraints, reliability, and cost, simultaneously. Aiming to address this grand and increasingly difficult challenge, the speaker will present multiple approaches centered around physical, architectural, and functional integration of advanced power management units with the systems that allow them to efficiently and essentially disappear/merge with the environment. Design examples and results from the iPower3Es group at UCSD and state-of-the-arts will also be covered as demonstration.
About the speaker:
Dr. Hanh-Phuc Le is an Assistant Professor of ECE at the University of California San Diego and a co-Director of the Power Management Integration Center, an NSF IUCRC center. He received the Ph.D. degree from UC Berkeley (2013), M.S. from KAIST, Korea (2006), and B.S. from Hanoi University of Science and Technology in Vietnam (2003), all in Electrical Engineering. In 2012, he co-founded and served as the CTO at Lion Semiconductor until October 2015. The company was acquired by Cirrus Logic in 2021. He was with the University of Colorado Boulder from 2016 to 2019, before joining the ECE department at UC San Diego. He held R&D and consulting positions at Oracle, Intel, Rambus, JDA Tech in Korea and the Vietnam Academy of Science and Technology (VAST) in Vietnam. His current research interests include miniaturized/on-die power conversions, large conversion ratios, smart power delivery and control for high performance IT systems, data centers, telecommunication, robots, automotive, mobile, wearable, and IoT applications.
Dr. Le received a 2021 NSF CAREER Award, a 2012-2013 IEEE Solid-State Circuits Society Pre-doctoral Achievement Award, and UC Berkeley’s 2013 Sevin Rosen Funds Award for Innovation. He authored three book chapters, over fifty journal and conference papers with one best paper award in various topics in the area of integrated power electronics. He is an inventor with 22 U.S. patents (11 granted and 11 pending). He serves as an associate editor of the IEEE Journal of Emerging and Selected Topics in Power Electronics (JESTPE), TPC Chair/co-chair for the International Workshop on Power Supply On Chip (PwrSoC 2018, 2020), Chair of the Power Management and Outreach Subcommittees at the IEEE Custom Integrated Circuits Conference (2020, 2021), Vice Chair of the Energy Conversion Congress and Exposition (ECCE) in 2021-2023, and Chair of the IEEE Power Electronics Society Technical Committee on Power Components, Integration, and Power ICs (IEEE PELS TC2) in 2019-2023. Dr. Le is an IEEE Senior Member.
