TDK Network Card iQN 35V 6A User Manual

Advance Product Brief: Supereta™ Series – Single Output High Current Quarter Brick  
Supereta™ iQN Series DC/DC Quarter Brick  
48V Input, 17V to 35V/6A DC Output  
The Supereta™ iQN Series offers an industry standard quarter  
brick high current power module with true useable output power.  
The iQN series power modules with the voltage foldback constant  
current limit feature are ideally suited for fan motor control and  
wireless applications. Its 90% efficiency and superior thermal  
performance make the iQN Series of power modules ideally suited  
for tight space and power-hungry applications in demanding  
thermal environments. This rugged building block is designed to  
serve as the core of high reliability system. The droop current  
sharing capability allows multiple modules to be connected in  
parallel. A wide output voltage trim down range, to 17V, and  
remote sensing are standard features enhancing versatility.
