Abstract
Pseudo-continuous control is developed for a regulated SC DC-DC converter using a three-stage switchable operational amplifier. The alternate switching of gain stages enables continuous output regulation in all clock phases. The converter achieves an output ripple of 20mV and output recovery time of ∼25μs for a load current of 50 to 150mA and switching frequency of 200 to 500kHz in 0.6μm CMOS.
