The LTC3703EG#PBF is a synchronous step-down Switching Regulator Controller that can directly step-down voltages from up to 100V, making it ideal. It drives external N-channel MOSFETs using a constant frequency (up to 600kHz), voltage mode architecture. A precise internal reference provides 1% DC accuracy. A high bandwidth error amplifier and patented line feed forward compensation provide very fast line and load transient response. Strong 1R gate drivers allow the controller to drive multiple MOSFETs for higher current applications. The operating frequency is user programmable from 100 to 600kHz and can also be synchronized to an external clock for noise-sensitive applications. Current limit is programmable with an external resistor and utilizes the voltage drop across the synchronous MOSFET to eliminate the need for a current sense resistor.
