INTEGRATED CHARGE-CONTROL SINGLE-INDUCTOR DUAL-OUTPUT STEP-UP/STEP-DOWN CONVERTER

摘要

An integrated charge-control single-inductor dual-output step-up/step-down converter that works in pseudo-continuous conduction mode is presented. The supply voltage is from 1.8V to 2.2V, with one output being 1.6V and the other 2.4V. It was designed using a 0.35μm process, and achieves an efficiency of 92% at a total load current of 160mA.
