MP9943

High Efficiency 3A Peak, 36V,

Synchronous Step Down Converter

With Power Good

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP9943 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 peak output

current with excellent load and line regulation

over a wide input supply range. The MP9943

has synchronous mode operation for higher

efficiency over the output current load range.



Wide 4V to 36V Continuous Operating Input

Range

85mΩ/55mΩ Low R_DS(ON)Internal Power

MOSFETs

High-Efficiency Synchron_{ous Mo}de Operation

410kHz Switching Frequency

Synchronizes from 200kHz to 2.2MHz

External Clock



High Duty Cycle for Automotive Cold-crank

Internal Power-Save Mode

Internal Soft-Start

Power Good Indicator

Over Current Protection and Hiccup

Thermal Shutdown

Output Adjustable from 0.8V

Available in an QFN-8 (3mmx3mm)

package

Current-mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over-current

protection and thermal shutdown.

The MP9943 requires a minimal number of

readily-available standard external components,

and is available in a space-saving QFN-8

(3mmx3mm) package.

APPLICATIONS
