Abstract

This paper presents a fully integrated single-inductor dual-output (SIDO) buck-boost or boost-boost DC-DC converter with power-distributive control. This converter works under voltage mode control to have better noise immunity, uses fewer power switches/external compensation components to reduce cost, and is thus suitable for system on chip (SoC) applications. The proposed SIDO converter was fabricated in TSMC 0.35 Â¿m 2P4M CMOS technology with input supply voltage 2.7-3.3 V. The first output V_O1 can operates either at buck mode or boost mode (output voltage in between 2.5 V to 5 V), while the second output V_O2 can only operates at boost mode (output voltage 3.6 V).
