ADP3198 Datasheet (Analog Devices) - 8-Bit Programmable 2- to 4-Phase Synchronous Buck Controller

ADP3198, 8-Bit Programmable 2- to 4-Phase Synchronous Buck Controller

The ADP31981 is a highly efficient, multiphase, synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors.

It uses an internal 8-bit DAC to read a voltage identification (VID) code directly f
