FAN5033 Datasheet (Fairchild Semiconductor) - Synchronous Buck Controller

FAN5033, Synchronous Buck Controller

The FAN5033 device is a multi-phase buck switching regulator controller optimized to convert a 12V input supply to the processor core voltage required by high ® performance Intel processors.

It has an internal 8-bit DAC that converts a digital voltage identification (VID) code, sent from the process

FAN5033 Features
