ADP3189 - Synchronous Buck Controller
The ADP3189 1 is a highly efficient multi-phase 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
