Overview

FAN5031 8-Bit Programmable, 2 to 4 Phase, Synchronous Buck Controller com March 2006 FAN5031 8-Bit Programmable, 2 to 4 Phase, Synchronous Buck Controller Features ■ Selectable 2, 3, or 4 phase operation at up to 1MHz ■ ■ ■ ■ ■ ■ ■ ■ Description The FAN5031 device is a multi-phase buck switching regulator controller, that is 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, that is sent from the processor, to set the output voltage between 0.
5V and 1.
6V in 6.
25 mV steps.
It outputs a PWM signals to external MOSFET driver...
