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