PRODUCT OVERVIEW
For applications requiring improved electrical and
thermal performance at reduced cost, consider
DATEL’s new UCQ series “quarter brick” DC-DC
power converters. These compact units measure
just 1.45" x 2.3" x 0.4" (36.8 x 60.9 x 10.2 mm)
and fit the industry-standard footprint.
Available outputs range between 1.2V @ 30 Amps
to 15V @ 6.7 Amps and accept a wide input range.
The UCQ’s interleaved, synchronous-rectifier
topology offers high efficiency (up to 93%), tight
line and load regulation, low noise and fast step
response. A single-board optimized open-frame
design contributes to impressive thermal opera-
tion. UCQ’s will operate up to +70°C and 100 LFM
airflow with no derating.
The UCQ’s feature full isolation to 2250Vdc
meeting BASIC insulation requirements of
UL/EN/IEC 60950-1. Input filters reduce propa-
gated switching noise back to input sources. Also
included is a remote On/Off switch control (with
positive or negative logic), output trim adjustable
over nominal and output sense functions to reduce
power lead losses. Extensive protection items
avoid damage from out of limit voltages, currents
and temperatures. Protection faults automatically
recover using the hiccup technique. Besides safety
testing to 60950-1, certifications for the UCQ in-
clude application for EMC compliance (to EN55022/
CISPR22 with filter), qualification testing.
