INNOVATION and EXCELLENCE

Single Output

UNS S e rie s

Non-Isolated, 3.3V and 5V

3 Amp, 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.

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 configura-

tions. 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-frequency (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.

Features

ꢀ

Low cost

SIP or DIP packaging

3.3V (10W) or 5V (15W) outputs

Wide range inputs:

4.75-13.6V for 3.3V models

6-16.5V for 5V models

High efficiencies, typically 90-92%

Low output noise, 50mVp-p

Remote on/off control

100µA "standby" input current

Output current limiting

EMC compliant

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.

Highly reliable, 100% SMT construction
