The ADP3168 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.
The ADP3168 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 features selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase with active current balancing between all output phases. It includes programmable short-circuit protection, a delayed Power Good output that accommodates on-the-fly output voltage changes requested by the CPU, and is specified over the commercial temperature range of 0°C to 85°C in a 28-lead TSSOP package.
