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.
densities and impressive MTBF’s. Their superior durability is substantiated by a
rigorous in-house qualifi cation program including HALT (Highly Accelerated Life
Testing). The goal of HALT is not to simulate fi eld conditions but to expose devices to
multiple excessive stresses with the intention of precipitating any potential electrical,
mechanical or process weaknesses.
these fully isolated (1500Vdc guaranteed) DC/DC’s offer excellent line/load regula-
tion, full I/O protection, and industry-standard pinouts.
