Abstract

This paper presents a monolithic single-stage, 4-phase switched-capacitor (SC) hybrid boost converter with 11-to- 20× voltage conversion ratios (VCRs). The 4-phase operating SC hybrid topology is proposed to achieve high VCRs with only three flying capacitors and one inductor. With the SC topology, the average inductor current and the inductor current ripple are much reduced, releasing both power loss and size requirement for the inductor. A four-phase pulse width modulation (PWM) controller is proposed. A successive ramp generation scheme ensures identical pulse widths across three consecutive phases. A driver-assisted auxiliary charge pump provides sufficient driving voltages for the high-side driver and simplifies the overall circuitry. The proposed hybrid boost converter was implemented in a 0.18 μm process. The measurement results show that the converter achieved a 20-24V output voltage range with a 1.2-1.8 V input voltage. 76.7%
