Corporate: www.cdtechno.com Corporate: www.cdtechno.com Product: www.cdpowerelectronics.com VSX75MD35 75 Watt Dual Output Quarter Brick DC/DC Converter 3.3V & 5.0V Dual Output 2.3" x 1.5" x 0.5" 90% Efficiency Low Output Noise Input Filtering VSX75 UL/CUL 1950, EN60 950 36-75 Vdc Input Models Continuous Short Circuit Protection Non-latching Protection: Input Undervoltage Input Overvoltage Output Overvoltage Overtemperature Output Voltage Tracking at Turn-on and Turn-off No Minimum Load Current Remote On/Off, Input Side Output Voltage Trim, +/-10% VSX75-U Fixed Frequency Operation -40C° to +100C° Baseplate Temp. Output Current Limit, Self-Start 1,500 Vdc Isolation, Input to Output APPLICATIONS Distributed Power Architectures Workstations EDP Equipment Telecommunications OPTIONS Choice of Remote On/Off Logic Configuration Heatsink Available for Extended Operation The VSX75 Series are 75 Watt, compact, high-efficiency, high-density dual output converters with a 36-75V input and with 3.3Vdc and 5.0Vdc outputs. The industry quarter-pack size of 2.3" x 1.5" x 0.5" coupled with 90% efficiency is an industry high-density breakthrough. These converters utilize V Series high density technology. This technology has been featured in our highly efficient VKP and VKA Series now successfully in use worldwide. The very high 90% efficiency minimizes the requirement for heat-sinking and the low output ripple minimizes the need for additional filtering. For maximum flexibility, power can be traded between outputs as required. The VSX75 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 VSX75 Series.
