Placing reliability and cost considerations above all others, DATEL’s new
A-Series DC/DC Converters combine straightforward circuit topologies, the newest
components, proven SMT-on-pcb construction, and highly repeatable automatic
assembly techniques. Considering the critical low-cost and long-term-reliability
requirements of today’s telecom, datacom and computer/networking applications,
the A-Series may well be the most cost-effective DC/DC’s available today.
The single-output, 6-10 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). The goal of HALT is not to simulate field conditions but to expose devices to
multiple excessive stresses with the intention of precipitating any potential electrical,
mechanical or process weaknesses.
Packaged in 2" x 1" x 0.375" shielded metal cases with non-conductive coatings,
these fully isolated (1500Vdc guaranteed) DC/DC’s offer excellent line/load regulation, full I/O protection, and industry-standard pinouts.
Output voltages include 5, 5.2, 12 and 15 Volts. Input voltage ranges are either
4.7-7.25V ("D5A" models), 9-18V ("D12A" models) or 18-75V ("D48A" models).
All A-Series UWR models are fully EMI characterized and UL1950, CSA950 and
IEC950 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.
