Overview
ADP3290 8-Bit, Programmable 2- to 4-Phase Synchronous Buck Controller The ADP3290 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−, 3− or 4−phase operation, allowing for the construction of up to fou...
