This datasheet describes the ADP3180, a multiphase synchronous buck switching regulator controller for Intel processors with programmable output voltage and…
The ADP3180 is a highly efficient multiphase synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors. It uses an internal 6-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.8375 V and 1.6 V.
The device uses a multimode PWM architecture to drive logic level outputs at a programmable switching frequency. It supports selectable 2-, 3-, or 4-phase operation, allowing for the construction of up to four complementary buck switching stages. The ADP3180 also includes programmable no-load offset and slope functions, accurate short circuit protection, and a delayed Power Good output.
