MP2345

26V, 2.5A, 600kHz, High-Efficiency,

Synchronous, Step-Down Converter

DESCRIPTION

FEATURES

The MP2345 is a high-efficiency, synchronous,

rectified, step-down, switch-mode converter

with built-in internal power MOSFETs. It offers a

very compact solution that achieves 2.5A of

continuous output current with excellent load

and line regulation over a wide input supply

range.



Wide 7.5V to 26V Operating Input Range

2.5A Load Current

90mΩ/40mΩ Low R_DS(ON)Internal Power

MOSFETs

Internal Power-Save Mode for Light Load

600kHz Fixed Switching Frequency at CCM

Optimized for Low EMI

Internal Soft Start

Over-Current Protection (OCP) and Hiccup

Mode



The MP2345’s switching edge is optimized for

low EMI. SW anti-ringing is employed to

address high-frequency radiation EMI issues.



Thermal Shutdown

Full protection features include over-current

protection (OCP) and thermal shutdown.

Output Adjustable from 3.3V

Available in a TSOT23-6 Package

The MPL-AL5050 Inductor Series Matches

Best Performance

The MP2345 requires a minimal number of

readily

available,

standard,

external

components and is available in a space-saving,

6-pin TSOT23 package.

APPLICATIONS



RF-Enabled Devices

Stand-By Power Supply

White Goods

Flat-Panel Television and Monitors
