MP9447  
High-Efficiency, Fast-Transient, 5A, 36V  
Synchronous, Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP9447 is  
a
fully-integrated, high-  
Wide 4.5V-to-36V Operating Input Range  
Guaranteed 5A, Continuous Output Current  
Internal 65mHigh-Side, 30mLow-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×VIN  
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
