ADP3168JRU

Product Summary

GENERAL DESCRIPTION :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, and uses a multimode PWM architecture to 
drive the logic-level outputs at a programmable switching frequency that can be optimized for VR size and efficiency. The phase relationship of the output signals can be programmed to
provide 2-, 3-, or 4-phase operation, allowing for the construction of up to four complementary buck switching stages. The ADP3168 also includes programmable no-load offset and 
slope functions to adjust the output voltage as a function of the load current so that it is always optimally positioned for a system transient. The ADP3168 also provides accurate and 
reliable short-circuit protection, adjustable current limiting, and a delayed Power Good output that accommodates on-the-fly
output voltage changes requested by the CPU.The device is specified over the commercial temperature range of 0°C to 85°C and is available in a 28-lead TSSOP package
