LTC3703EGN-5#PBF

LINEAR TECHNOLOGY  LTC3703EGN-5#PBF  直流/直流控制器, 4V至15V, 1路输出, 同步降压, 330kHz, SSOP-16

The 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.
