Product Summary
The mp1593dn-c061-lf-z is a Step-Down Converter. The mp1593dn-c061-lf-z is a step-down regulator with an internal Power MOSFET. It achieves 3A 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. Adjustable soft-start reduces the stress on the input source at turn-on. In shutdown mode the regulator draws 20μA of supply current. The mp1593dn-c061-lf-z requires a minimum number of readily available external components to complete a 3A step down DC to DC converter solution. The applications of the mp1593dn-c061-lf-z include Distributed Power Systems, Battery Chargers, Pre-Regulator for Linear Regulators, Flat Panel TVs, Set-Top Boxes, Cigarette Lighter Powered Devices and DVD/PVR Devices.
