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.
