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.

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.

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.

The UCQ’s feature full isolation to 2250Vdc

... See Performance/Functional Specifications. Output Over-Voltage Protection The UCQ output voltage is monitored for an over-voltage condition using a com- parator. The signal is optically coupled to the primary side and if the output volt- age rises to a level which could be damaging to the load, the sensing circuitry will power down the PWM controller causing the output voltage to decrease ...

... OUT OUT Trimming Output Voltage UCQ converters have a trim capability (pin 6) that enables users to adjust the output voltage (refer to the trim equations and trim graphs that follow). Adjust- ments to the output voltage can be accomplished via a trim pot (Figure single fixed resistor as shown in Figures 6 and 7. A single fixed resistor can increase or decrease the output voltage depending on its connection. Resistors should be located close to the converter and have TCR’ ...
