LTC3824EMSE#PBF

LTC3824 is a step-down DC/DC controller designed to drive an external P-channel MOSFET. Constant frequency current mode operation provides excellent performance. This device 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 upto 600KHz and is easily synchronizable. Other features include current limit, soft-start, micropower shutdown, and Burst Mode disable. It is widely used in application such as industrial and automotive power supplies, telecom power supplies, distributed power systems etc.
