MP2325

High Efficiency 3A, 24V, 500kHz

Synchronous Step-Down Converter

DESCRIPTION

FEATURES

The MP2325 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 3A continuous

output current over a wide input supply range

with excellent load and line regulation. The

MP2325 has synchronous mode operation for

higher efficiency over output current load range.



Wide 4.5V to 24V Operating Input Range

90mΩ/40mΩ Low Rds(on) Internal Power

MOSFETs

Low Quiescent Current

High Efficiency Synchronous Mode

Operation

Fixed 500kHz Switching Frequency

Frequency Sync from 200kHz to 2MHz

External Clock

Power Save Mode at light load

Internal Soft Start

Power Good Indicator

OCP Protection and Hiccup

Thermal Shutdown



Current mode operation provides fast transient

response and eases loop stabilization.



Full protection features include OCP and

thermal shut down.

The MP2325 requires a minimum number of

readily available standard external components

and is available in a space saving 8-pin

TSOT23 package.

Output Adjustable from 0.8V

Available in an 8-pin TSOT-23 package

APPLICATIONS



Notebook Systems and I/O Power

Digital Set Top Boxes

Flat Panel Television and Monitors
