MP1593 General Description

The MP1593 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 lineregulation.

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 20A of supply current. The MP1593 requires a minimum number of readily available external components to complete a 3A step down DC to DC converter solution.
