摘要

A switched capacitor (SC)-based converter with an integrated switch is proposed to improve the efficiency of the traditional SC converter. The proposed converter has the properties of fast transient responses and nonpulsating output current, which can reduce both the output voltage ripple and current stress requirement of the output capacitor. The proposed converter has been implemented using the Taiwan Semiconductor Manufacturing Company Technology Corporation 0.35-$mu{rm m}$ 3.3/5 V 2P4M CMOS process. The switching frequency is 1 MHz with a 150-mA maximum load current for 3.3-V input and 1.0–4.5-V output range application. The experimental results prove that the power efficiency of the proposed scheme can be up to 90%.
