DESCRIPTION

The MP2234 is a high-frequency, synchronous,

rectified,

step-down,

switch-mode

converter

with built-in power MOSFETs. It offers a very

compact solution to achieve a 2A continuous

output current with excellent load and line

regulation over a wide input supply range. The

MP2234 has synchronous mode operation for

higher efficiency over the output current load

range.

Current-mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over-current

protection and thermal shut down.

The MP2234 requires a minimal number of

readily-available standard external components,

and is available in a space-saving 8-pin

TSOT23 package.
