New Super-Wide 8:1 Input Range DC/DC Converters Set New Benchmark

18-135V input range with up to 90% efficiency; 9 output voltages; power levels from 90-200W; InQor® industry-standard half-brick format

SynQor’s latest  family of industry-standard half brick ac/dc converters feature a super-wide 8:1 input voltage range of 18-135V, which doubles the existing ultra-wide 4:1 input ratio standard. With a single SynQor IQ64 converter designers are able to simultaneously satisfy EN50155 requirements for 36V, 48V and 72V railway systems.

Setting a new performance benchmark for half brick dc/dc converters the IQ64 family uses SynQor’s patented two-stage topology with a constant mid-bus voltage, which enables an optimized isolation stage design based on synchronous rectifiers, greatly reducing heat loss and achieving up to 90% efficiency at full load. IQ64 converters are available in1.8V, 3.3V, 5V, 12V, 15V, 24V, 28V, 40V and 48V variants, each variant is available with a power rating in the 200W range, and for lower power requirements in a cost-optimized 150W unit.

The feature rich IQ64 series of dc/dc converters provides on/off control referenced to input side, remote sense for the output voltage and an output voltage trim range of -20%, +10%. Protection features include input under-voltage lockout, input over-voltage shutdown, output current limit and short circuit protection, active back bias limit, output over-voltage protection and thermal shutdown. All models have at least 2250Vdc isolation rating between input and output, have calculated MTBF values in excess of 2MHrs, and are fully 6/6 RoHS compliant.

The IQ64 series is available today for evaluation and qualification. Lead times for production quantities are in the range 8-12 weeks depending upon volumes. For more details please use the more information service below.
