ANDOVER, Mass., 18 Oct. 2006. Vicor Corp. in Andover, Mass., added eight mid-power Maxi DC-DC converters to the company's 24 volts DC input family: a 3.3 Vout, 200 W model and 300-Watt models at 5, 12, 15, 24, 28, 36, and 48 Vout.
The modules -- which incorporate Vicor's patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) topology -- are appropriate for defense, aerospace, communications, industrial or process control, distributed power, medical, and ATE applications.
Low-noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements. With switching frequencies as high as 1 MHz, the 24 volts DC family provides rapid transient response well suited for RF applications.
With these new models, the 24 Vin Maxi family now comprises 16 models with output voltages from 3.3 to 48 volts DC and power levels from 200 to 400 Watts. The converters operate from 24 volts nominal input, with an input range of 18 to 36 volts.
Efficiencies range up to 88 percent for the higher output voltages. These models are available in five different environmental grades, with six different 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 available in RoHS compliant models, are a compact 4.6-by-2.2-by-0.5 inch (117-by-56-by-12,7 millimeters) in size with a height above board of 0.43 inch .
"Designers who don't need the full-power capability of a 24 V Maxi module now have the availability of a mid-power Maxi with all of the functionality and configurability of the high power models," says Robert Marchetti, Vicor's manager of product marketing.
