DESCRIPTION

The

MP2235S

is

a

high-frequency,

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

readily

available,

standard,

external

components and is available in a space-saving

8-pin TSOT23 package.

FEATURES
