ADP3191 Datasheet (Analog Devices) - Synchronous Buck Controller

ADP3191, Synchronous Buck Controller

The ADP3191/ADP3191A1 are highly efficient, multiphase, synchronous buck switching regulator controllers optimized for converting a 5 V or 12 V main supply into the core supply voltage required by high performance Intel processors.

They use an internal 6-bit DAC to read a voltage identification (VID
