MP2308

18V, 4A Synchronous

Step-Down Coverter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2308 is a synchronous rectified step-

down switch mode converter with built in

internal power MOSFETs. It offers a very

compact solution to achieve 4A continuous

output current over a wide input supply range

with excellent load and line regulation. The

MP2308 has synchronous mode operation for

higher efficiency over output current load range.



Wide 4.75V to 18V Operating Input Range

EN ON/OFF Control

Light Load Mode Selectable

External Soft Start



Current mode operation provides fast transient

response and eases loop stabilization. Full

protection features include OCP and thermal

shut down.

APPLICATIONS



DSL Modems

Cable Modems

Set Top Boxes

The MP2308 requires a minimum number of

readily available standard external components

and is available in a space saving 2mm x 3mm

14-pin QFN package.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green
