The MP2363 is a non-synchronous step-down regulator with an integrated 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 MP2363 requires a minimum number of readily available external components to complete a 3A step-down DC to DC converter solution.
