Description
The FAN5029 is a highly efficient multi-phase synchronous buck switching
regulator controller optimized for converting a 12V main supply into the core supply voltage required by high performance Intel processors.
It uses an internal 8-bit DAC to read voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.
5V and 1.
6V.
It uses a multi-mode PWM architecture to drive the logic-leve...
