MP2228

High-Efficiency, 2A, 16V, 800kHz

Synchronous, Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2228 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

MP2228 has synchronous mode operation for

higher efficiency over the output current load

range.

•

6V-to-16V Operating Input Range

100mΩ/40mΩ Low R_DS(ON)Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Operation

Fixed 800kHz Switching Frequency

•

Current-mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over-current

protection and thermal shut down.

APPLICATIONS

The MP2228 requires a minimal number of

readily-available standard external components,

and is available in a space-saving 8-pin

TSOT23 package.
