Abstract

This paper presents a peak current-controlled (PCC) single-inductor dual-output (SIDO) DC-DC buck converter with a time-multiplexing (TM) scheme. Small signal modeling, system compensation, and circuit implementation are discussed. Simulation and measurements confirm the effectiveness of the proposed method. The converter was fabricated using TSMC 0.35-μm CMOS technology. The input supply voltage is from 2.7-4.2V. Two outputs are specified at 2.5V/36mA and 1.8V/20mA, respectively, and operated at 500 KHz with a 1-μH inductor and 20-μF capacitors.
