An 85-230VAC input and 3.3-4.6VDC output AC-DC converterOct. 2023 - Oct. 2024
- A Sigma-Floating-SC topology is proposed to achieve 81.3\% peak efficiency and 1.52W maximum output power.
- Up to 10% increased efficiency over a large load current range, compared with prior works.
- The design is fabricated in a 180nmBCD process and the manuscript has been accepted by ISSCC 2025.
