Available in a 8-pin TSOT-23 Package
synchronous, rectified, step-down, switch-mode
converter with built-in power MOSFETs. It
offers a compact solution to achieve a 3 A
continuous output current with excellent load
and line regulation over a wide input supply
range. The MP2235S 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 (OCP) and thermal shutdown (TSD).
The MP2235S requires a minimal number of
APPLICATIONS
readily
available,
standard,
external
components and is available in a space-saving
8-pin TSOT23 package.
