MP2225

High-Efficiency, 5A, 18V, 500kHz

Synchronous, Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2225 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 5A output current

with excellent load and line regulation over a

wide input supply range. The MP2225 has

synchronous mode operation for higher

efficiency over the output current load range.

•

Wide 4.5V-to-18V Operating Input Range

Adjustable Output Voltage as low as 0.6V

Low 47mΩ/18mΩ R_DS(ON)of Internal Power

MOSFETs

•

High Efficiency up to 97%

Fixed 500kHz Switching Frequency

Synchronizes from a 200kHz-to-2MHz

External Clock

•

2.4ms Internal Soft-Start Time

1% Reference Accuracy at Room

Temperature

Internal Power-save Mode

OCP with hiccup mode

Current-mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over-current

protection and thermal shut down.

•

The MP2225 requires a minimal number of

readily-available standard external components,

and is available in a space-saving 8-pin

TSOT23 package.

Available in 8-pin TSOT23

APPLICATIONS

•

Flat-Panel Television and Monitors

Notebook Systems and I/O Power

Digital Set-Top Boxes

Distributed Power Systems
