ADP3181 Datasheet - Analog Devices

ADP3181 5-Bit or 6-Bit Programmable 2-/3-/4-Phase Synchronous Buck Controller

The ADP3181 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 6-bit DAC to read a voltage identification (VID) code directly from.
