MP38870数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The MP38870 is a monolithic step-down switch mode converter with a built in internal high-side power MOSFET. It achieves 3A 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. Fault condition protection includes cycle?y?ycle current limiting and thermal shutdown. The MP38870 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 14-pin QFN package.
