Q48T30018 DC-DC Converter Data Sheet  
36-75 VDC Input; 1.8 VDC @ 30A Output  
The Q48T30018 through-hole mounted DC-DC converter  
offers unprecedented performance in the industry-standard  
quarter brick format. This is accomplished through the use of  
patent pending circuit and packaging techniques to achieve  
ultra-high efficiency, excellent thermal performance and a  
very low body profile.  
&&  
In telecommunications applications theQFamily 30 A con-  
verters provide thermal performance that far exceeds all  
quarter bricks and is comparable even to existing half-bricks.  
Low body profile and the preclusion of heat sinks minimize  
airflow shadowing, thus enhancing cooling for downstream  
devices. The use of 100% surface-mount technologies for  
assembly, coupled with Power-One’s advanced electric and  
thermal circuitry and packaging, results in a product with ex-  
tremely high quality and reliability.
