Single Output, High Reliability, 2" x 2", 14-20 Watt, DC/DC Converters
PRODUCT OVERVIEW
DATEL's new A-Series switching DC/DC converters are designed to meet the demanding long-
term-reliability and low-cost requirements of modern telecom,
datacom, computer/networking and industrial-electronics applications. These highly-effi cient, rugged
devices combine straightforward circuit topologies, new components, proven SMT-on-pcb construc-
tion methods, and highly repeatable automatic-assembly techniques. The fl exibility of the designs and
their assembly methods readily permit
minor modifi cations to optimize performance for specifi c applications.
The single-output, 14-20 Watt Models of the A-Series deliver both high power densities and
impressive MTBF’s.
Packaged in standard, 2" x 2" x 0.45", shielded metal cases with non-conductive coatings, these
fully isolated (1500Vdc minimum) DC/DC’s offer excellent line/load regulation, full I/O protection,
thermal shutdown, and industry-standard pinouts.
Output voltages include 3.3, 5, 5.2, 12 or 15 Volts. Input voltage ranges are DATEL's traditional
ultra-wide 9-36V and 18-75V, as well as 4.7-7.5V. Each device provides remote on/off control and
V
trim capability. All A-Series UWR models are fully EMI characterized and designed to meet
OUT
UL1950, CSA 950 and IEC 950 safety.
A-Series DC/DC’s are extremely reliable, easy-to-use, cost-effective power converters. Use them
to improve the reliability of existing equipment or to develop
new systems that exceed design objectives.

UWR-3.3/4850-D48A (18-75V input, curve A) and UWR-3.3/4850-D12A (9-36V input, curve A) will derate curve AA if used over the limited input ranges of 20-60V or 10-30V, respectively. 2. "D48A" models (18-75V input ranges) that derate along curve B will derate along curve BB if used over the more limited input range of 24-60V. ...

    ... Filtering and Noise Reduction All A-Series UWR 14-20 Watt DC/DC Converters achieve their rated ripple and noise specifi cations without the use of external input/output capaci- tors. In critical applications, input/output noise may be further reduced by installing electrolytic capacitors across the input terminals and/or low-ESR tantalum or electrolytic capacitors across the output terminals ...

    ... Input Fusing Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. For DATEL A-Series UWR 14-20 Watt DC/DC Converters, you should use slow-blow type fuses with values no greater than the following: V Range Fuse Value IN D5A ...
