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 supe rior 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 droo p 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.
