TD1741 is a Synchronous Buck Controller with two currentsense pins suitable for many multi‐output applications. It isdesigned to allow for operating a wide supply voltage rangefrom 6V to 40V. It has both high‐side and low‐side driversallowing synchronous configuration using two externalpower‐NMOS。This IC can operate in both Constant Current(CC) and Constant Voltage (CV) modes.TD1741 operates as a Buck Controller providing a wide rangeof outputs at Constant Voltage (CV) from 6V to 40V and theoutput current as high as 10A or above. It has a ConstantCurrent (CC) mode so that output current can be setexternally and at an accuracy of ±4%. The current mode control and external compensation makesfeedback control have good line and load regulation withflexible external design.
