DESCRIPTION
The MP1583 is a step-down regulator with a built-in internal Power
MOSFET. It achieves 3A of 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. An adjustable soft-start reduces the stress
on the input source at startup. In shutdown mode the regulator
draws 20μA of supply current.
The MP1583 requires a minimum number of external components,
providing a compact solution.
