MP2318
High Efficiency 2A, 24V, 2MHz
Synchronous Step-Down Converter
DESCRIPTION
The MP2318 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 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.
Full protection features include OCP and
thermal shut down.
The MP2318 requires a minimum number of
readily available standard external components
and is available in a space saving 8-pin
TSOT23 package.
