MP2363DN-LF-Z Datasheet, PDF (1/13 Pages) MPS Industries, Inc. – 3A, 27V, 365KHz Step-Down Converter

The Future of Analog IC Technology
DESCRIPTION
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.
The MP2363 is available in 8-pin SOICN and
PDIP packages.
