MP4420H

High Efficiency 2A, 36V,

Synchronous Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The

MP4420H

high-frequency,

•

Wide 4V to 36V Continuous Operating Input

Range

90mΩ/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

synchronous, rectified, step-down, switch-mode

converter with built-in power MOSFETs. It

offers a very compact solution to achieve a 2A

continuous output current with excellent load

and line regulation over a wide input supply

range. The MP4420H has synchronous mode

operation for higher efficiency over the output

current load range.

•

High Duty Cycle for Automotive Cold-crank

Power-Save Mode

Internal Soft-Start

Power Good

OCP Protection and Hiccup

Thermal Shutdown

Current-mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over-current

protection and thermal shut down.

The MP4420H requires a minimal number of

readily-available standard external components,

and is available in a space-saving TSOT23-8

package.

Output Adjustable from 0.8V

Available in an 8-pin TSOT23-8 package
