Vicor Corp. in Andover, Mass., is adding six mid-power Micro DC-DC converters to the 48 volts DC input family: a 50-watt model at 3.3 volt and 75-watt models at 12, 15, 24, 28, and 48 volts. The modules, which incorporate Vicor’s low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS), are appropriate for power-system applications in distributed power, medical, ATE, communications, defense, and aerospace. Low-noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements. With these new models, the 48 Vin Micro family now comprises 16 models with output voltages from 2 to 48 volts DC and power levels from 50 to 150 watts. The converters operate from 48 volts nominal input, with an input range of 36 to 75 volts. Efficiencies range up to 89 percent for the higher output voltages. These models are available in five different environmental grades, with six pin options, and three baseplate options. They can be configured in any combination in Vicor’s Custom Module Design System at www.vicorpower.com. The modules, which are optionally available in RoHS compliant models, are a compact 2.28 by 1.45 by 0.5 inches. For more information contact Vicor online at www.vicorpower.com.
