FAN5033 Product details

Description
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 processor, to set the output voltage between 0.5V and 1.6V in 6.25mV steps. It outputs PWM signals to external MOSFET drivers that drive the switching power MOSFETs. The switching frequency of the design is programmable by a single resistor value. The number of phases can be programmed to support two- or three-phase applications.

Features
■ Selectable 2- or 3-phase operation at up to 1MHz per phase
■ ±7.7mV worst-case differential sensing error over temperature
■ Active current balancing between the output phases
■ Power Good and Crowbar blanking supports on-the-fly VID code changes
■ 0.5V to 1.6V output
■ Fully compliant with the Intel® VR10 and VR11 specifications
■ Selectable VR10 extended (7-bit) and VR11 (8-bit) VID tables
■ Programmable soft-start ramp
■ Programmable short-circuit protection and latch-off delay

Applications
■ Desktop PC/Server processor power supplies for existing and next-generation Intel processors
■ VRM modules
