Abstract
A buck voltage regulator control circuit for a single-input multi-output direct current power supply system, during a soft start phase of a first buck voltage regulator of the power supply system, the buck voltage regulator control circuit controls a first high side switch of the first buck voltage regulator to switch to a turned-on state from a turned-off state when a second high side switch of a second buck voltage regulator is in the turned-off state. Therefore, the first and second high side switches are not simultaneously switched to the turned-on state from the turned-off state to reduce inrush current.
