ADP3207CJCPZ-RL

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.
