Circuit Description

The LTC3877 + LTC3874 are used to provide power for the Core Rail by taking advantage of the 6-bit parallel VID that interfaces with the 20-nm Arria 10’s SmartVID to reduce the FPGA’s static and dynamic power consumption, and Ultralow value and temperature compensated DCR load current sensing which maximizes the efficiency and load current sharing precision.
