MP4423A

3A, 36V, High-Efficiency,

Synchronous, Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP4423A is a high-efficiency, synchronous,

rectified, step-down, switch-mode converter

with built-in power MOSFETs. It offers a very

compact solution that achieves 3A of

continuous output current with excellent load

and line regulation over a wide input supply

range.



Wide 4V to 36V Continuous Operating Input

Range

85mΩ/55mΩ Low R_DS(ON)Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Operation

Default 410kHz Switching Frequency

Synchronizes to a 200kHz to 2.2MHz

External Clock

High Duty Cycle for Automotive Cold Crank

Forced CCM Mode

Internal Soft Start

Power Good

Over-Current Protection (OCP) and Hiccup

Thermal Shutdown



The MP4423A uses synchronous mode

operation to achieve higher efficiency over the

output current load range. Current-mode

operation provides fast transient response and

eases loop stabilization.



Full protection features include over-current

protection (OCP) and thermal shutdown.

The MP4423A requires a minimal number of

Output Adjustable from 0.8V
