MP1583中文资料3A, 23V, 385kHz Asynchronous Step-Down Converter数据手册MPS规格书

描述 Description

The MP1583 is a step-down regulator with a built in internal Power MOSFET. It achieves 3A of continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle?y?ycle current limiting and thermal shutdown. An adjustable soft-start reduces the stress on the input source at startup. In shutdown mode the regulator draws 20? of supply current. The MP1583 requires a minimum number of external components, providing a compact solution.
