Overview

TD1741 is a Synchronous Buck Controller with two current sense pins suitable for many multi‐output applications. It is designed to allow for operating a wide supply voltage range from 6V to 40V. It has both high‐side and low‐side drivers allowing synchronous configuration using two external power‐NMOS. This IC can operate in both Constant Current (CC) and Constant Voltage (CV) modes. TD1741 operates as a Buck Controller providing a wide range of outputs at Constant Voltage (CV) from 6V to 40V and the output current as high as 10A or above. It has a Constant Current (CC) mode so that output current can be set externally and at an accuracy of ±4%. The current mode control and external compensation makes feedback control have good line and load regulation with flexible external design.

Applications

Car Charger
High‐Brightness Lighting
General‐Purpose DC/DC Controller
