Overview

FAN5032 8-Bit Programmable 2 to 4 Phase Synchronous Buck Controller April 2006 FAN5032 8-Bit Programmable 2 to 4 Phase Synchronous Buck Controller Features ■ Selectable 2, 3, or 4 phase operation at up to 1MHz ■ ■ ■ ■ ■ ■ ■ ■ Description The FAN5032 is a controller for a multi-phase buck switching regulator optimized to convert a 12V input supply to the processor core voltage required by highperformance Intel processors.
It has an internal 8-bit digital to analog converter (DAC) that converts a digital voltage identiﬁcation (VID) code, sent from the processor to set the output voltage between 0.
5V and 1.
6V in 6.
25mV steps.
It outputs a pulse-width modulated (PWM) signal to external MOSFET...
