The A-Series dual DC/DC converters combine straightforward circuit topologies, the newest components, proven SMT-on-pcb construction methods, and highly repeatable auto- matic-assembly techniques, they are highly efficient, rugged, and have a long lifespan.
The A‑Series BWR family provides compact 2" × 1" × 0.375" dual‑output DC/DC converters that deliver +5 V, +12 V or +15 V at up to 10 W per output. They feature fully isolated 1500 Vdc isolation, high efficiency (up to 82 %), and built‑in protections such as reverse‑polarity shutdown and over‑voltage limiting. The converters are RoHS‑compliant and designed for battery‑powered or distributed power applications in telecom, computer, instrumentation and ATE markets.
Performance specifications include wide input voltage ranges (4.7‑7.25 V, 9‑18 V, 18‑75 V), tight output voltage accuracy, low ripple/noise, and operation from –40 °C to +65/70 °C (derated to +100 °C). Mechanical details, pin‑out diagrams, and recommended external filtering are provided, along with information on custom‑cap options, quality‑assurance processes, and HALT testing used to ensure reliability.
