14-20 Watt, DC/DC Converters

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 by a
rigorous in-house qualification program including HALT (Highly Accelerated Life Test
ing), 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 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

OUT trim capability. All A-Series UWR models are

fully EMI characterized and UL1950, CSA 950 and IEC 950 safety approved.

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

1. 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.
