MPQ2315GJ-Z Datasheet, PDF (1/21 Pages) MPS Industries, Inc. – High Efficiency 3A, 24V, 500kHz Synchronous Step Down Converter

The Future of Analog IC Technology
DESCRIPTION
The MPQ2315 is a high frequency synchronous
rectified step-down switch mode converter with
built in internal power MOSFETs. It offers a
very compact solution to achieve 3A continuous
output current over a wide input supply range
with excellent load and line regulation. The
MPQ2315 has synchronous mode operation for
higher efficiency over output current load range.
Current mode operation provides fast transient
response and eases loop stabilization.
Full protection features include OCP and
thermal shut down.
The MPQ2315 requires a minimum number of
readily available standard external components
and is available in a space saving 8-pin
TSOT23 package.
