Description

The MP1583 is a step-down regulator with a built in internal Power MOSFET. It achieves 3A continuous output current over a wide input supply range with excellent load and line regulation.

Current mode operation MP1583 provides fast transient response and eases loop stabilization.

Fault condition protection MP1583 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 MP1583 requires a minimum number of readily available external components to complete a 3A step down DC to DC converter solution.
