MP1411DH-LF-Z

MP1411 2A, 18V, 380KHz Step-Down Converter The Future of Analog IC TechnologyTM DESCRIPTION The MP1411 is a monolithic step-down switch mode converter 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 23μA of supply current. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup. The MP1411 requires a minimum number of readily available standard external components.
