Maxeta iFA Series DC-DC Power Modules

24V Input, 28V Output, 602W Full Brick

The Maxeta iFA series power modules are

ideally suited for wireless applications to power

RF power amplifiers. With a typical 89% full

load efficiency (90% at 80% load), a power

density of 108W per cubic inch and a total

power and current output capability of 602W

and 21.5A respectively, the Maxeta Series

offers the highest efficiency, power density and

usable output power for 24V input applications

in a standard full brick package currently

available. A wide output voltage trim range, -

40% to +10%, remote sensing, and isolated

remote on/off control are standard features

enhancing versatility. The Maxeta iFA series

power modules are also suited for other

telecommunication applications.
