ADP3210 7-Bit, Programmable, Multiphase Mobile CPU Synchronous Buck Controller The ADP3210 is a high efficiency, multiphase, synchronous, buck−switching regulator controller optimized for converting notebook battery voltage into the core supply voltage of high performance Intel processors. The part uses an internal 7−bit DAC to read Voltage Identification (VID) code directly from the processor that sets the output voltage. The phase relationship of the output signals can be configured for 1−, 2−, or 3−phase operation, with interleaved switching. The ADP3210 uses a multi−mode architecture to drive the logic−level PWM outputs at a switching frequency selected by the user depending on the output current requirement.
