General Description
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.
