APPLICATIONS  
mA p-p  
The B-NXT-1W series are miniature,1W  
DC/DC converters with high isolation in a  
SMD package. With a new package design  
these converters are qualified for the higher  
temperatures requested by lead-free reflow  
solder processes. With the small footprint,  
these converters are the ideal solution for  
board level power distribution,mainly for  
applications in the industrial and telecom  
field. For automated SMD production lines  
the devices can be supplied in standard  
tape and reel package.
