GENERAL DESCRIPTION

The ADP3180 is a highly effi cient multiphase synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high per formance Intel processors. It uses an internal 6-bit DAC to read a voltage identifi cation (VID) code directly from the processor, which is used to set the output voltage between 0.8375 V and 1.6 V, and uses a multimode PWM architecture to drive the logic level outputs at a programmable switching frequency that can be

optimized for VR size and efficiency.

FEATURES

Selectable 2-, 3-, or 4-Phase Operation at up to 1 MHz per Phase
