MP28275  
7V, 5A, 1.1MHz  
Synchronous Step-down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28275 is a high frequency synchronous  
rectified step-down switch mode converter with  
built-in internal power MOSFETs. It offers a  
very compact solution to achieve 5A continuous  
output current with excellent load and line  
regulation. The MP28275 operates at high  
efficiency over a wide output current load range.  
4.5V to 7V Operating Input Range  
5A Output Current  
Low RDS(ON) Internal Power MOSFETs  
Proprietary Switching Loss Reduction  
Technique  
Fixed 1.1MHz Switching Frequency  
Sync from 300kHz to 2MHz External Clock  
Internal Compensation  
Current mode operation provides fast transient  
response and eases loop stabilization.  
Thermal Shutdown  
Over-Current-Protection and Hiccup  
Output Adjustable from 0.8V  
Available in 3x4mm QFN14 Package  
Full protection features include OCP and thermal  
shut down.  
The MP28275 requires a minimum number of  
readily available standard external components  
and is available in a space saving 3mm x 4mm  
14-pin QFN package.
