Synchronous, Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP9447 is

fully-integrated, high-



Wide 4.5V-to-36V Operating Input Range

Guaranteed 5A, Continuous Output Current

Internal 65mΩ High-Side, 30mΩ Low-Side

Power MOSFETs

Proprietary Switching-Loss-Reduction

Technology

1.5% Reference Voltage

Programmable Soft-Start Time

Low Drop-out Mode

200kHz-to-650kHz Switching Frequency

SCP, OCP, UVP, and Thermal Shutdown

Output Adjustable from 0.8V to 0.9×V_IN

Available in a 3×4mm 20-pin QFN Package

frequency, synchronous, rectified, step-down,

switch-mode converter. It offers a very compact

solution to achieve a 5A, continuous-output

current over a wide input-supply range with

excellent load and line regulation. It also

provides fast transient response and good

stability for wide input-supply and load range.

The MP9447 operates at high efficiency over a

wide output current load range.



Full protection features include SCP, OCP, UVP,

and thermal shutdown.

The MP9447 requires a minimal number of

readily-available, standard, external components,

and is available in a space-saving 3mm×4mm,

20-pin, QFN package.

APPLICATIONS



General Consumer

USB Power Supplies

Cigarette Lighter Adapters

Power Supply for Chargers
