Low-Proﬁle, Quarter Brick, 8.3-40 Amp

Isolated DC/DC Converters

Typical units

FEATURES

PRODUCT OVERVIEW

nꢀ

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.

The UCQ’s feature full isolation to 2250Vdc

meeting BASIC insulation requirements of

Standard quarter-brick package/pinout

nꢀ

Low cost; Low proﬁle, 0.4" (10.2mm)

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

Outputs: 1.2V to 12V

nꢀ

Interleaved synchronous-rectiﬁer topology

• Ultra high efﬁciency

• No output reverse conduction

Available outputs range between 1.2V @ 30 Amps

to 12V @ 8.3 Amps and accept a wide input range. power lead losses. Extensive protection items

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.

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.
