MP1423DN datasheet


Description :

The MP1423DN 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 MP1423 requires a minimum number of readily available external components to complete a 3A step-down DC to DC converter solution.
