描述 Description

The MP38872 is a monolithic step-down switch mode converter with a built in high-side internal power MOSFET and a gate driver for a low-side external MOSFET. It achieves 6A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and reliable over-current protection. The MP38872 requires a minimum number of readily available standard external components and is available in a 14-pin QFN 3x4mm package with exposed pad.
