OBSOLETE PRODUCT Corporate: www.cdtechno.com Contact factory for replacement model VSX40MD23C 40 Watt Dual Output Quarter Brick DC/DC Converter APPLICATIONS Distributed Power Architectures Workstations EDP Equipment Telecommunications OPTIONS Choice of Remote On/Off logic Configuration Heatsink Available for Extended Operation 2.5V & 3.3V Dual Output 2.3" x 1.5" x 0.5" 90% Efficiency Low Output Noise Input Filtering Remote On/Off, Input Side Output Voltage Trim, +/-10% Fixed Frequency Operation -40C° to +100C° Baseplate Temp. Output Current Limit, Self-Start 1,500 Vdc Isolation, Input to Output The VSX40C series are dual output converters having two input ranges, either 18-36V or 36-75V. The units dual asymmetric output voltages are 5V and 3.3V. The converter features an industry-standard quarter-brick size (2.3" x 1.5" x 0.5") coupled with 90% efficiency. These converters utilize Vx high density technology. This technology has been featured in our highly efficient VKP and VKA series now successfully in use worldwide. The very high efficiency minimizes the requirement for heatsinking and the low output ripple minimizes the need for additional filtering. For maximum flexibility, power can be traded between outputs as required. The VSX40C series feature virtually all of the options required by design engineers but not at the competition’s typical additional price for each option. This multitude of features are standard on the VSX40C series.
