Single-Inductor Quad-Output Switching Converter With Priority-Scheduled Program

Abstract

System-on-a-chip (SoC) applications require multiple power supply voltages with the features of low no ise for analog cir- cuits and high efficiency for digital circuits. Thus, this paper pro- poses the priority-scheduled program (PSP) for the single-inductor quad-output (SIQO) switching converter . This technique manages energy delivery to multiple outputs, facilitates fast transient re- sponse, and reduces cross-regulati on simultaneously. Moreover , a level bypass detector (LBD) is used to o v
