Monolithic Power Systems
General Description
The MP1410 is a monolithic step-down switch-
mode regulator with a built in internal Power
MOSFET. It achieves 2A 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. In
shutdown mode the regulator draws 25µa of
supply current.
The MP1410 requires a minimum number of
readily available standard external components.
