19.1 Piggybacked SC-on-CSCR: A Modular On-Chip Switched-Capacitor Converter for 12-to-60V Input 1.8-to-5V Output Achieving 5.67mW/mm2 Power Density and 71.5% Peak Efficiency
Abstract
This paper presents an on-chip switched-capacitor converter, named piggybacked SC-onCSCR, featuring: 1) a power density of 5.67 mW/mm2enabled by eliminating high-voltage switches and jointly utilizing MOM and MOS capacitors; 2) a 12-to-60V input and 1.8-to-5V output achieved through a chip-level modular design; 3) 71.5% peak efficiency enabled by full soft-charging operation; and 4) fast high-voltage startup protection, verified under a 20 V/ms power-on slope.
