MP2380 5A, 21V, 600KHz Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP2380 is a monolithic step-down switch Wide 4.5V to 21V Operating Input Range mode converter with a built in high-side power 5A Continuous Output Current MOSFET. It achieves 5A continuous output 45m Internal Power MOSFET Switch current over a wide input supply range with Power Good Indicator excellent load and line regulation. Fixed 600KHz Frequency Synchronizable Up to 1.5 MHz Current mode operation provides fast transient Cycle-by-Cycle Over Current Protection response and eases loop stabilization. Thermal Shutdown Fault condition protection includes cycle-by-cycle Output Adjustable from 0.8V current limiting and thermal shutdown. Stable with Low ESR Output Ceramic The MP2380 requires a minimum number of Capacitors readily available standard external components Available in a Thermally Enhanced 8-Pin and is available in an 8-pin SOIC package with SOIC Package exposed pad.
