ADP3293
ADP3293 is Programmable 2- to 3-Phase Synchronous Buck Controller manufactured by onsemi.
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...
