These units are ideally suited for
telecommunications, distributed power
systems, automatic test equipment,
medical and process control.
Applications
Fifteen models available; Three input
voltage ranges of 4.5-5.25 Vdc, 9-36
Vdc, and 20-72 Vdc provide regulated
outputs of 5, 12, 15 and ±12 and ±15
Vdc.
These high performance 5 watt con-
verters offer a high switching frequency
topology, 500 Vdc I/O isolation, and
efficiencies to 75%.
he QA series of cost
sensitive single and dual output
5 watt DC/DC converters are
specifically designed for critical appli-
cations requiring a compact, low profile
case.
