Single Output, Low-Proﬁle, Quarter-Brick

8-25 Amp Isolated DC-DC Converters

To Be Discontinued*

Typical units

Features

For applications requiring improved electrical and thermal perfomance at reduced cost DATEL's

new ULQ Series "Quarter-Brick" DC-DC Converters suit perfectly. They measure just 1.45 x 2.30 x

0.35 inches (36.8 x 58.4 x 8.9mm) and ﬁt the industry-standard footprint. You can also "pick-and-

place" the ULQ-SMT version optimizing your automated SMT process.

From an 18-36V or 36-75V input, ULQ's deliver outputs of 1.2, 1.5, 1.8, or 2V fully rated at 15 or

25A, 2.5 or 3.3V at 15 or 20A, 5V at 15A and 12V at 8-10A. They

employ an interleaved, synchronous-rectiﬁer topology that exploits 100% of their duty cycle. They

simultaneously achieve ultra-high efﬁciency (to 91%), tight line/load regulation ( 0.125/0.25%), low

noise (25-70mVp-p), and quick step response (200µsec).

A state of the art, single-board, open-frame design with reduced component count, high

efﬁciency, low-on-resistance FET's, and planar magnetics embedded in heavy-copper pc boards all

contribute to impressive thermal derating.

Outstanding thermal performance

On/off control, trim & sense functions

Fully isolated, 2250Vdc (BASIC)

Output overvoltage protection

Fully I/O protected; Thermal shutdown

UL/EN/IEC60950 safety approvals

Qual/HALT/EMI tested

The ULQ's feature set includes high isolation (2250Vdc), input pi ﬁlters, input undervoltage shut-

down, output overvoltage protection, current limiting, short-circuit protection and thermal shutdown.

The standard footprint carries on/off control (positive or negative logic), output trim (+10/–20%) and

output sense functions.

All ULQ quarter-bricks are designed to meet the BASIC-insulation requirements of UL/EN/

IEC60950 and they will carry the CE mark. Safety certiﬁcations, EMC compliance testing and qualiﬁ-

cation testing (including HALT) are currently in progress. Contact DATEL for latest updates.
