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 12V @ 8.3 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 polarity), 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 include application for EMC compliance (to FCC class B), qualification testing (including HALT) and CE marking.
