IP개요 This proposal presents an adaptive gate driver-assisted continuously scalable-conversion-ratio (CSCR) switched-capacitor (SC) DC-DC converter. Gate-source voltage controller (GSVC) generates dynamic supply voltage to the gate driver adaptively according to the output voltage level of the converter. By adopting an adaptive gate driver to achieve soft charging between capacitor connections, the overall system generates a wide range of output with high power density and power conversion efficiency. The proposed converter generates an output ranges from 0.5 V to 2 V with an input voltage range from 2.5 V to 3.3 V. The proposed converter achieves a peak PCE of 85 % and exhibits a maximum IOUT of 800 mA. The proposed converter is implemented in TSMC 180 nm BCD process, with a chip area of 5x5 mm2.
