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 highly­efficient, rugged devices combine straightforward circuit topologies, new components,
proven SMT-on-pcb construction 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 . Their superior durability is substantiated b y a rigorous
in-house qualification program including HAL T (Highly Accelerated Lif e Testing), which is
designed to detect any potential electrical, mechanical, or process weaknesses.

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 e xcellent 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 D ATEL'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
characterized and UL1950, CSA 950 and IEC 950 safety approved.

A-Series DC/DC’s are extremely reliable , easy-to-use, cost-effectiv e power
converters. Use them to improve the reliability of existing equipment or to develop
new systems that exceed design objectives.
