CONTROL

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.

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.

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

coated for protection against moisture and dust.

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.

This designation is not used in the ordering model number – it only appears on the device itself. These changes were unavoidable because of obsolescence of the PWM controller. ...
