LTC3703EGN#TRPBF

LTC®3703 is a synchronous step-down switching regulator controller that can directly step down voltages from up to 100V, making it ideal for telecom and automotive applications. This 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 feedforward compensation provide very fast line and load transient response. 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. Application includes 48V telecom and base station power supplies, networking equipment, servers, automotive and industrial control.
