iQN 35V/6A Advance Product Brief 9/17/2004

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.
