Document Type and Number:
Japanese Patent JP2003527809
Kind Code:
A
Abstract:
An integrated circuit (IC) switching power converter includes a main power supply for providing a main voltage output and an auxiliary power supply for providing an auxiliary voltage output lower than the main voltage output. All of the integrated components of the main power supply and the auxiliary power supply are formed in a single IC die which is mounted in a single IC package. For improved economy and/or efficiency, the main power supply and the auxiliary power supply can share external electrical connection pins, and the two power supplies may also share circuitry.
