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 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 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 UL1950, CSA 950 and IEC 950 safety approved.
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.
