Vicor Introduces New Mid-Power 24 Vin Maxi Modules

Vicor Corp. announced the addition of eight mid-power Maxi dc-dc converters to the 24Vdc input family: a 3.3 Vout, 200 and 300W models at 5, 12, 15, 24, 28, 36, and 48Vout. The modules — which incorporate Vicor's patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) topology — are appropriate for industrial or process control, distributed power, medical, ATE, communications, defense, and aerospace 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 up to 1MHz, the 24Vdc family provides rapid transient response well-suited for RF applications.

With these new models, the 24Vin Maxi family now comprises 16 models with output voltages from 3.3 to 48Vdc and power levels from 200 to 400W. The converters operate from 24V nominal input, with an input range of 18V to 36V. Efficiencies range up to 88% 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 via the company's website. The modules, which are available in RoHS compliant models, are a compact 4.6 x 2.2 x 0.5 inch (117 x 56 x 12,7 mm) in size with a height above board of 0.43 inch (10,9 mm).

"Designers who don't need the full-power capability of a 24V Maxi module now have the availability of a mid-power Maxi with all of the functionality and configurability of the high power models," said Robert Marchetti, Manager, Product Marketing.

The new mid-power Maxis are available from stock to 6 weeks lead times and are priced from $105 in quantities of 1000.
