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

VOUT 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.
