PRINTER POWER SUPPLY USING VIPer53
John S. Lo Giudice




INTRODUCTION
The VIPer53 combines in the same package an enhanced current mode PWM controller with a high
voltage MDMesh Power Mosfet. This application note describes the implementation of the VIPer53 in a
printer power supply that has peak power requirements up to 45W. Since the VIPer53 has MOSFET that
has a maximum Rdson of 1 max at 1A, the DIP-8 will handle the power requirements without an added
