MP9943A

High Efficiency 3A Peak, 36V,

Synchronous Step-Down Converter

With Power Good

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The

MP9943A

high-frequency,



Wide 4V to 36V Continuous Operating Input

Range

85mΩ/55mΩ Low RDS(ON) Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Operation

410kHz Switching Frequency

Synchronizes from 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 3A

peak output current with excellent load and line

regulation over a wide input supply range. The

MP9943A has synchronous mode operation for

higher efficiency over the output current load

range.



High Duty Cycle for Automotive Cold-crank

Force CCM Mode

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 MP9943A requires a minimal number of

readily-available standard external components,

and is available in a space-saving QFN-8

(3mmx3mm) package.

APPLICATIONS



General Consumer

Multi-Function Printers (MFP)

Distributed Power Systems
