onsemi ADP3207D
The ADP3207D 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.| Part No. | ADP3207D |
