Description
The QLS15 is a series of highly efficient, cost-effective, low-profile, single-output dc-dc converters in an industry-
standard, quarter-brick footprint. The QLS15 Series provides onboard conversion of standard telecom and
datacom input voltages into isolated low voltage outputs in a through-hole mounting package. Patent pending
technology, combined with state-of-the-art packaging techniques, allow the QLS15 Series to deliver full-rated
output, without the need for a heat sink at 70°C and 200 LFM airflow.
