LTC3824MPMSE#PBF Datasheet PDF - Linear Technology

The LTC3824MPMSE#PBF is a step-down DC/DC Controller designed to drive an external P-channel MOSFET. It features a wide input range of 4 to 60V and a high voltage gate driver. The 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.
