MP28251  
20V, 4A Synchronous  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28251 is a synchronous, rectified, step-  
down, switch-mode converter with internal  
power MOSFETs. It offers a very compact  
solution to achieve a 4A continuous output  
current over a wide input supply range with  
excellent load and line regulation. The  
MP28251 has synchronous mode operation for  
higher efficiency over the output current load  
range.  
Wide 4.75V-to-20V Operating Input Range  
4A Output Current  
Low RDS(ON) Internal Power MOSFETs  
Programmable Switching Frequency  
Programmable EN Delay  
Frequency SYNC from 300kHz to 2MHz  
External Clock  
Low Power Mode Selectable by an External  
Signal  
Current-mode operation provides  
a
fast  
External Soft Start  
OCP and Thermal Shutdown  
Available in a 14-pin QFN2×3 Package  
transient response and eases loop stabilization.  
Full protection features include over-current  
protection and thermal shutdown.  
APPLICATIONS  
The MP28251 requires a minimal number of  
readily-available standard external components  
and is available in a space saving 2mm×3mm  
14-pin QFN package.
