Product Summary
The mp1593dn-lf-z is a step-down regulator with an internal Power MOSFET. The mp1593dn-lf-z achieves 3A of 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. An adjustable soft-start reduces the stress on the input source at startup. In shutdown mode the regulator draws 20μA of supply current. The mp1593dn-lf-z requires a minimum number of readily available external components, providing a compact solution. The applications of the mp1593dn-lf-z are: Distributed Power Systems, Battery Chargers, Pre-Regulator for Linear Regulators, Flat Panel TVs, Set-Top Boxes, Cigarette Lighter Powered Devices, DVD/PVR Devices.
