MP4423

High Efficiency 3A, 36V,

Synchronous Step Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP4423 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 3A continuous

output current with excellent load and line

regulation over a wide input supply range. The

MP4423 has synchronous mode operation for

higher efficiency over the output current load

range.

•

Wide 4V to 30V Continuous Operating Input

MOSFETs

High-Efficiency Synchronous Mode

Operation

Default 410kHz Switching Frequency

Synchronizes to a 200kHz to 2.2MHz

External Clock

•

Current-mode operation provides fast transient

response and eases loop stabilization.

•

High Duty Cycle for Automotive Cold-crank

Power-Save Mode

Internal Soft-Start

Power Good

OCP Protection and Hiccup

Thermal Shutdown

Output Adjustable from 0.8V

Available in an QFN-8 (3mmx3mm)

package

Full protection features include over-current

protection and thermal shut down.

The MP4423 requires a minimal number of

readily-available standard external components,

and is available in a space-saving QFN-8

(3mmx3mm) package.
