The ADP3290 is a highly efficient multiphase 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 code directly from the processor to set the output voltage between 0.5 V and 1.6 V. This device uses a multimode 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 four complementary buck switching stages.The ADP3290 also includes programmable no load offset and load line slope setting function that adjusts the output voltage as a function of the load current optimally positioning it for a system transient. The ADP3290 also provides accurate and reliable short circuit protection adjustable current limit and a delayed power-good output that accommodates on-the-fly output voltage changes requested by the CPU.
