Abstract

This paper describes a time-limited one-shot current control technique used to extend the outputs of a single-inductor multiple-output DC-DC converter without stability and complexity issues. The proposed scheme also reliably supports many outputs with unbalanced loads. True all-comparator control is realized with a single shared hysteresis comparator and a fixed switching frequency of 800-kHz. The maximum efficiency reaches 92%. The fabricated 8-channel output chip occupies 2.4×2.1 mm2 in a 0.35-μm CMOS process.
