Abstract

A single-inductor dual-output (SIDO) step-down DC-DC converter with continuous conduction mode (CCM) operation is proposed to improve efficiency and reduce cost for power management applications. The designed converter has a supply voltage from 2.7 V to 3.3V with dual output voltages at 1.8V and 1.2V. The pulse frequency modulation (PFM) technique is employed to reduce cross regulation between dual outputs. The proposed SIDO converter has been demostrated with 0.35μm CMOS process for a system-on-chip (SoC) design.
