DESCRIPTION

The MP1496 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 2A continuous

output current with excellent load and line

regulation over a wide input supply range. The

MP1496 has synchronous mode operation for

higher efficiency over the output-current–load

range.

Current-mode

operation

provides

a

fast

transient response and eases loop stabilization.

Protective

features

include

over-current

protection and thermal shut down and external

SS control.

The MP1496 requires a minimal number of

readily-available standard external components,

and is available in a space-saving 8-pin

TSOT23 package.
