LTC3824 Datasheet PDF

●The LTC3824EMSE#PBF is a high voltage step-down DC/DC Controller with 40µA quiescent current designed to drive an external P-channel MOSFET. With a wide input range of 4 to 60V and a high voltage gate driver, the LTC3824 is suitable for many industrial and automotive high power applications. Constant frequency current mode operation provides excellent performance. The LTC3824 can be configured for Burst Mode® operation. Burst Mode® operation enhances low current efficiency (only 40µA quiescent current) and extends battery run time. The switching frequency can be programmed up to 600kHz and is easily synchronizable. Other features include current limit, soft start, micropower shutdown and Burst Mode® disable.
