The MP2380 is a monolithic step-down switch mode converter with a built in high-side power MOSFET. It achieves 5A 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-by-cycle current limiting and thermal shutdown. The MP2380 requires a minimum number of readily available standard external components and is available in an 8-pin SOIC package with exposed pad.
