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-efficient, rugged
devices combine straightforward circuit topologies, new components, proven SMT-on-pcb construc-
tion methods, and highly repeatable automatic-assembly techniques. The flexibility of the designs and
their assembly methods readily permit
minor modifications to optimize performance for specific 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

trim capability. All A-Series UWR models are fully EMI characterized and designed to meet
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.
