Multi-Output Switching Regulator and Multi-Output Power Supply Method

Abstract

The present invention discloses a multi-output switching regulator and a multi-output power supply method. The multi-output switching regulator includes: a power stage circuit for operating at least a power switch included therein and only one inductor included therein in response to a pulse width modulation (PWM) signal, thereby converting an input voltage to a converted voltage; a multiple outputs circuit for receiving the converted voltage to generate a plurality of output currents; a voltage detecting circuit for generating a feedback signal according to the converted voltage; and a PWM signal generation circuit for generating the PWM signal in response to the feedback signal.
