TD1489规格书详情
描述 Description
TD1489 is a Synchronous Buck Circuit with two current sense pins suitable for many multi‐output applications. It is designed to allow for operating a wide supply voltage range from 4.7V to 40V.This IC can operate in both Constant Current (CC) and Constant Voltage (CV) modes. TD1489 operates as a Buck Circuit providing a wide range of outputs at Constant Voltage (CV) from 4.7V to 40V and the output current as high as 6A 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.
