DESCRIPTION

The MP2313 is a high frequency synchronous

rectified step-down switch mode converter with

built-in internal power MOSFETs. It offers a

very compact solution to achieve 1A continuous

output current over a wide input supply range

with excellent load and line regulation.

Current mode operation provides fast transient

response and eases loop stabilization.

Full protection features include OCP and

thermal shut down.

The MP2313 requires a minimum number of

readily available standard external components

and is available in a space saving TSOT23-8

package.
