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.
