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. MP1583 MP3202DJ-LF-Z MP1593 MP1580 MP2359 MP1540 等MPS全系列供应
