The MP2377 is a monolithic step-down switch mode converter with a built in 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 eases loop stabilization. Fault condition protection includes current limiting and thermal shutdown. The MP2377 requires a minimum number of readily available standard external components and is available in 8-pin SOIC packages with exposed pad.
