DESCRIPTION

The

MP1475S

is

a

high-frequency,

synchronous, rectified, step-down, switch-mode

converter with built-in power MOSFETs. It

offers a compact solution to achieve a 3A

continuous output current with excellent load

and line regulation over a wide input-supply

range. The MP1475S 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 shut down (TSD).

The MP1475S requires a minimal number of

readily

available,

standard,

external

components and is available in a space-saving

8-pin TSOT23 package.
