ADP3293
8-Bit, Programmable 2- to 3-Phase Synchronous Buck Controller
The ADP3293 is a highly efficient, multi−phase, synchronous buck switching
regulator controller optimized for converting a 12 V main supply voltage into the core supply voltage of high performance Intel processors.
It uses an internal 8−bit DAC to read a voltage identification (VID) code directly from the processor, to set the output voltage between 0.
5 V and 1.
6 V.
This device uses a multi−mode control architecture to drive the logic−level PWM outputs.
The switching frequency can be programmed according to VR size and efficiency.
The chip can provide 2− or 3−phase operation, allowing for the construction of up to four co...
