1 / 9 page  MP1410 2A Step-Down Switch-Mode Regulator PRELIMINARY MP1410 Rev 1.0_ 05/29/02 www.monolithicpower.com 1 Monolithic Power Systems General Description The MP1410 is a monolithic step-down switch- mode regulator with a built in internal Power MOSFET. It achieves 2A 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. In shutdown mode the regulator draws 25µa of supply current. The MP1410 requires a minimum number of readily available standard external components.
