The 1/8th-brick SQL48T20033 and the 1/16th-brick SSQL48T20033 dc/dc converters are rated at 20 A, provide an adjustable 3.3-V isolated output and operate over the full 36- to 75-V telecom input voltage range. They suit telecom and datacom systems targeting access, backbone, networking equipment and cellular infrastructure. The converters are DOSA compliant, with outstanding thermal performance for use at elevated temperatures or in applications with reduced airflow.
The converters withstand a 100-V input transient for 100 ms, meet EN 60950 basic insulation requirements, are UL94 V-0 flammability rated, operate down to no load conditions and will start up into pre-biased loads. They are fully protected including hiccup-mode overcurrent, output overvoltage, input undervoltage lockout and overtemperature shutdown. The dc/dc converters optional baseplate feature is ideal for extreme environmental applications found in 3G and 4G/LTE wireless communication deployments. Evaluation models are available now.
