UNS Series

Non-Isolated, 3.3V & 5V, 3A DC/DC Converters

Low cost, high efﬁciency, wide input voltage range and low output

noise deﬁne DATEL’s new UNS Series of non-isolated, step-down,

switching DC/DC converters.

FEATURES

PRODUCT OVERVIEW

The 3.3V- and 5V-output devices are, respectively,

90% and 92% efﬁcient. All models are fully line

and load regulated and maintain speciﬁed accuracy

over the impressively wide input voltage ranges of

4.75 to 13.6 Volts for 3.3V outputs and 6 to 16.5

Volts for 5V outputs. Output ripple and noise are

typically 50mVp-p.

coated for protection against moisture and dust.

nꢀLow cost

The high efﬁciency of the UNS Series’ ﬁxed-fre-

quency (190kHz) switching design eliminates the

need for thermally conductive potting compound.

Devices are speciﬁed for full-power operation up

to ambient temperatures of +50°C. With derating,

they operate up to +70°C. Calculated MTBF (MIL-

HDBK-217F) is more than 1.6 million hours.

These simple-to-use power converters have no

minimum load requirements. They draw 1mA when

unloaded and a mere 100µA in the standby mode

(On/Off Control turned off). 3.3V models have an

output voltage adjustment range of 2.7 to 3.3 Volts.

5V models are adjustable down to 3.0V.

nꢀSIP or DIP packaging

nꢀ3.3V (10W) or 5V (15W) outputs

nꢀWide range inputs:

4.75-13.6V for 3.3V models

6-16.5V for 5V models

UNS devices are fabricated using proven SMT-

on-pcb construction techniques. The 3.3V and 5V

devices are both available in either lightweight SIP

(2" x 0.4" x 0.8") or DIP (2" x 0.8" x 0.4", 600 mil

spacing between rows) package conﬁgurations.

The DIP option is designated by a "D" sufﬁx added

to the part number. All models are conformally

nꢀHigh efﬁciencies, typically 90-92%

nꢀLow output noise, 50mVp-p

nꢀRemote on/off control

nꢀ100µA "standby" input current

nꢀOutput current limiting

nꢀEMC compliant

nꢀHighly reliable, 100% SMT construction

nꢀConformally coated for harsh environments
