LTC3703EGN-5#PBF (LINEAR TECHNOLOGY)

The LTC3703EGN-5#PBF is a synchronous step-down Switching Regulator Controller that can directly step-down voltages from up to 60V, making it ideal for telecom and automotive applications. The LTC3703-5 drives external logic level 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 1W gate drivers allow the LTC3703-5 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.
