DESCRIPTION

The

MP1495S

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 3A

continuous output current with excellent load

and line regulation over a wide input supply

range. The MP1495S 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 MP1495S requires a minimal number of

readily-available standard external components,

and is available in a space-saving 8-pin

TSOT23 package.
