MP4470/4470A  
High-Efficiency, Fast-Transient, 5A, 36V  
Synchronous, Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP4470/4470A is a fully-integrated, high-  
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 MP4470/4470A operates at high efficiency  
over a wide output current load range.

•
Wide 4.5V-to-36V Operating Input Range  
Guaranteed 5A, Continuous Output Current  
Internal 40mΩ High-Side, 20mΩ Low-Side  
Power MOSFETs  
Proprietary Switching-Loss-Reduction  
Technology  
1% Reference Voltage  
Programmable Soft-Start Time  
Low Drop-out Mode  
200kHz-to-1MHz Switching Frequency  
SCP, OCP, OVP Latch(MP4470 only), UVP,  
and Thermal Shutdown  
Output Adjustable from 0.8V to 0.9×VIN  
Available in a 3×4mm 20-pin QFN Package
