INNOVATION and EXCELLENCE

Single Output

USQ 40A Models

High-Current, Quarter-Brick

40 Amp, DC/DC Converters

An unrivaled combination of power, size, long-term reliability and affordable cost

deﬁnes DATEL’s new 40 Ampere output series Quarter-Bricks. By exploiting a fully

synchronous forward topology and the newest available components, the USQ 40A

model converters achieve an 89% efﬁciency. The extremely high efﬁciency enables

these units to reliably deliver up to 40 Amps of output power from a low-height

proﬁle, industry-standard “quarter-brick” format package (1.45" x 2.28" x 0.40") with

aluminum baseplate and open-to-airﬂow shell. The USQ 40A models are a pin-

compatible, high-current, companion product family to DATEL’s USQ 30A and 20A

families, and the ULQ Series 10A and 15A family of quarter bricks.

Additional features include output noise of 110 millivolts, 0.05% line/load regu-

lation maximum, and quick transient response (200µsec to 1%). Device functionality

includes remote on/off control (positive or negative polarity), and output trim (+10%,

–20%), sense function, and nominal input ranges of 24V (18-36V) and 48V (36-75V).

In order to safeguard both the power converter and its load, USQ 40A models,

offers the most extensive I/O protection including input undervoltage lockout, and

reverse-polarity protection, as well as output overvoltage protection, current limiting,

short-circuit protection (“hiccup” technique), and thermal shutdown (and optional

input overvoltage lockout).

The USQ 40A Series are designed to meet the BASIC insulation requirements of

UL1950 and EN60950. The “D48” models carry the CE mark. Safety certiﬁcations, as

well as EMC compliance testing and qualiﬁcation testing (including HALT), have been

successfully completed. Contact DATEL for the latest information.
