7-Bit Programmable, Multi-Phase Mobile, CPU Synchronous Buck Controller

The ADP3207C is a high efficiency, multi?phase, synchronous, buck?switching regulator controller optimized for converting notebook battery voltage into the core supply voltage required by high performance Intel processors. The part uses an internal 7?bit Digital?to?Analog Converter (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 programmed to provide 1?, 2?, or 3?phase operation, allowing for the construction of up to three interleaved buck?switching stages.
