The MP28490 is a monolithic step-down switch mode converter with a built in internal 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 MP28490 requires a minimum number of readily available standard external components and is available in an 8-pin SOIC package with exposed pad.Wide 4.5V to 30V Operating Input Range 5A Output Current 50m? Internal Power MOSFET Switch Power Good Indicator Fixed 420kHz Frequency Synchronizable up to 1.5MHz Cycle-by-Cycle Over Current Protection with hiccup Thermal Shutdown Output Adjustable from 0.8V to 15V Stable with Low ESR Output Ceramic Capacitors Available in a Thermally Enhanced 8-Pin SOIC Package
