2 to 4-Phase Synchronous Buck Controller

The ADP3196 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 Advanced Micro Devices, Inc. (AMD) processors. It uses an internal 6-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.3750 V and 1.55 V.
