The BXA200 Series of high density DC/DC converters uses Artesyn Technologies
patented resonant transition zero voltage switching topology together with advanced
packaging to provide high performance with a power density of 36Watts/in3. Fixed
frequency operation at 500kHz together with our unique integrated magnetics and
internal filters, facilitate easier system filtering, limiting input conducted noise to
EN55022 level A. Zero voltage switching together with advanced power train design
minimizes power losses, yielding efficiencies up to 85% , from a 4.6 x 2.4 x 0.5 inch
industry standard package. The BXA200 series with six single output models from
3.3V to 48V, offer short circuit protection, overvoltage protection, true current sharing,
redundancy and up to 40A capability, all of which simplify and accelerate design-in
cycles, reduce component counts, save PCB space and increase system reliability,
giving you the lowest overall cost of ownership with the shortest possible time to
market.
