Abstract

See full text

A power supply system has a first power circuit, a second power circuit, a first controller and a second controller. The first and second power circuits respectively have a first and second plurality of switching circuits coupled in parallel to provide an output voltage. The first controller provides a turn-on control signal at the first turn-on control pin based on a voltage feedback signal received by a first feedback pin, and provides a first plurality of switching control signals at the first plurality of switching control pins based on a turn-on control signal to successively turn ON a first plurality of switching circuits. The second controller provides a second plurality of switching control signals at a second plurality of switching control pins based on the turn-on control signal received by a second turn-on control pin to successively turn ON the second plurality of switching circuits.
