PRODUCT OVERVIEW

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.

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.

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

The UEP Series DC/DC Converters deliver

By combining a high-frequency (340kHz),

Output voltages are 3.3, 5, 12 or 15 Volts.

... This on/off cycling is referred to as "hiccup" mode. The hiccup cycling reduces the average output current, thereby preventing internal temperatures from rising to excessive levels. The UEP is capable of enduring an indefinite short circuit output condition. Thermal Shutdown These UEP converters are equipped with Thermal Shutdown Circuitry. If envi- ronmental conditions cause the internal temperature of the DC/DC converter rises above the designed operating temperature (typically 118° ...
