PRODUCT OVERVIEW
The UEP Series DC/DC Converters deliver
the most power/current (up to 30W/6Amps)
from a 1" x 2" package. And because of their
footprint compatibility, they can be used as
drop in replacements for their bigger brothers,
the standard 2" x 2" and 1.6" x 2" devices,
commonly used in the industry.
By combining a high-frequency (340kHz),
high-efficiency (to 89%), synchronous-rectifier
topology with the newest components and
time-tested, fully automated, SMT-on-pcb
construction, these UEP Models are able
to bring you 15-30W in the standard 2" x 1"
package from which most competitors can
only get 5-10W. All UEP’s deliver their full
output power over ambient temperature
ranges from –40°C to as high as +70°C
(model and input voltage dependent) without
heat sinks or supplemental forced-air cooling.
Devices derate to +100°C.
Output voltages are 3.3, 5, 12 or 15 Volts.
Input voltage ranges are 10-18V (“D12”
models), 18-36V (“D24” models) or 36-75V
(“D48”) models. All models feature input pi
filters, input undervoltage and overvoltage
lockout, input reverse-polarity protection,
output overvoltage protection, output current
limiting, and continuous short-circuit protection.
Standard features also include on/off control
and output-trim. All models are certified to
IEC950, UL1950 and EN60950 safety require-
ments for OPERATIONAL insulation. “D48”
models (36‑75V inputs) are CE marked.
UEP Series DC/DC’s are packaged
in low-cost, light-weight, diallyl phthalate
(UL94V-0 rated) plastic packages with stand-
offs. EMC compliance is achieved via a low-
noise design rather than through expensive
metal shielding.

➀ 3.3V and 5V-output models use the synchronous-rectifier configuration shown above.
12V and 15V-output models employ a standard, diode-rectification architecture.
