HPH Series  
.
Isolated, Low VOUT to 70A, Half-Brick DC/DC Converters  
Murata Power Solutions’ fully isolated HPH series of DC/DC converters affords users a  
practical solution for their low-voltage/high-current applications. With an input voltage range of  
36 to 75 Volts, the HPH Series delivers up to 70 Amps of output current from a fully regulated  
3.3V output.  
PRODUCT OVERVIEW  
Typical unit  
Using both surface-mount technology  
and planar magnetics, these converters  
are manufactured on a 2.3" x 2.4", lead-  
These DC/DC’s provide output trim,  
sense pins and primary side on/off con-  
trol (available with positive or negative
