The Supereta™ iQN Series offers an industry standard quarter
brick high current power module with true useable output power.
Its 92% typical efficiency, a power density greater than 118W per
cubic inch, output voltage fold-back current limit feature, and
superior thermal performance make the iQN Series of power
modules ideally suited for wireless
applications to power various
RF amplifiers. This rugged building block is designed to serve as
the core of the high reliability system. The droop current sharing
capability allows multiple modules connected in parallel to be
possible. A wide output voltage trim range, -40 to +10%, remote
sensing, and remote ON/OFF control are standard features
enhancing versatility.
