Abstract

A switching power supply converts DC to DC voltages. The switching power supply has multiple phase time delayed voltage generating circuits and a single switching power supply regulator circuit. The multiple phase time delayed voltage generating circuits are then synchronized with a pulse period of the switching power supply regulator circuit to achieve the conversion.
