The Future of Analog IC Technology
DESCRIPTION
The MP2225 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 5A output current
with excellent load and line regulation over a
wide input supply range. The MP2225 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 MP2225 requires a minimal number of
readily-available standard external components,
and is available in a space-saving 8-pin
TSOT23 package.
