MP2403

3A, 32V, 250kHz Integrated Synchronous

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2403 is a monolithic synchronous buck

regulator. The device integrates a 150mΩ

high-side MOSFET and an 80mΩ low-side

MOSFET that provides 3A continuous load

current over a wide operating input voltage of

4.6V to 32V. Current mode control provides fast

transient response and cycle-by-cycle current

limit.



3A Output Current

Wide 4.6V to 32V Operating Input Range

Integrated MOSFET Switches

Output Adjustable from 0.80V to 28V

Up to 95% Efficiency

Programmable Soft-Start

Stable with Low ESR Ceramic Output Capacitors

Fixed 250kHz Frequency

Cycle-by-Cycle Over Current Protection

Input Under Voltage Lockout

An adjustable soft-start prevents inrush current

at turn-on. In shutdown mode, the supply

current drops to 1μA.

Thermally Enhanced 8-Pin SOIC Package

This device, available in an 8-pin SOIC

package, provides a very compact system

solution with minimal reliance on external

components.

APPLICATIONS



Distributed Power Systems

Pre-Regulator for Linear Regulators

Notebook Computers
