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 1.8 V to 2.2 V, with one output being 1.6 V and the other 2.4 V. It was designed using a 0.35 /spl mu/m process, and achieves an efficiency of 92% at a total load current of 160 mA.
