MP9442

High Efficiency 2A, 36V, 600kHz

Synchronous Step-Down Converter

with Power Good

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP9442 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 2A continuous

output current with excellent load and line

regulation over a wide input supply range. The

MP9442 has synchronous mode operation for

higher efficiency over the output current load

range.

•

Wide 4V to 36V Continuous Operating Input

Range

90mΩ/55mΩ Low RDS(ON) Internal Power

MOSFETs

High-Efficiency Synchronous Mode

Operation

600kHz Switching Frequency

Synchronizes from 200kHz to 2.2MHz

External Clock

•

High Duty Cycle for Automotive Cold-crank

Internal Power-Save Mode

Over-Current Protection with Hiccup

Thermal Shutdown

Current-mode operation provides fast transient

response and eases loop stabilization.

Full protection features include over-current

protection and thermal shutdown.

The MP9442 requires a minimal number of

readily-available standard external components,

and is available in a space-saving 8-pin

TSOT23 package.

Output Adjustable from 0.8V

Available in an 8-pin TSOT-23 package
