The MP38891 is a monolithic step-down switch mode converter with a built in internal power MOSFET. It achieves 6A 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 MP38891 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 14-pin QFN package.Wide 4.5V to 30V Operating Input Range 6A Output Current 50m? Internal Power MOSFET Switch Synchronizable Gate Driver Delivers up to 95% Efficiency Fixed 420kHz Frequency Synchronizable up to 1.4MHz Cycle-by-Cycle Over Current Protection Thermal Shutdown Output Adjustable from 0.8V to 15V Stable with Low ESR Output Ceramic Capacitors Available in a Thermally Enhanced 3mm x 4mm 14-Pin QFN Package
