DESCRIPTION The MP1410 is a monolithic step-down switch mode converter with a built in internal power MOSFET. It achieves 2A continuous output cur-rent over a wide input supply range with excel-lent load and line regulation. The MP1410 requires a minimum number of readily available standard external components. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 25μA of supply current. FEATURES 2A Output Current 0.22? Internal Power MOSFET Switch Stable with Low ESR Output Ceramic Capacitors Up to 92% Efficiency 25μA Shutdown Mode Fixed 390KHz Frequency Thermal Shutdown Cycle-by-Cycle Over Current Protection Wide 4.75 to 23V Operating Input Range Output Adjustable from 1.22V to 21V APPLICATIONS Automotive Power Adapters PDA and Cellular Phone Battery Chargers Distributed Power Systems Automotive Aftermarket Electronics |
