Vicor has added eight mid-power Maxi DC/DC converters to its 375Vdc input family: a 200W model at 3.3Vout, a 300W model at 5Vout, and 400W models at 12, 15, 24, 28, 36, and 48Vout. The modules — which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) — are appropriate for off-line systems with auto-ranging or PFC front ends in industrial or process control, distributed power, medical, ATE, communications, defence and aerospace applications.

With these new models, the 375Vin Maxi family now comprises 17 models with output voltages from 2 to 54Vdc and power levels from 160 to 600W. The converters operate from 375V nominal input, with an input range of 250V to 425V. Efficiencies range up to 89% 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.vicoreurope.com.

Designers who do not need the full-power capability of a 375V Maxi module now have the availability of a mid-power Maxi with all of the functionality and configurability of the high power models. In addition, the low noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements.

The modules, which are available as RoHS compliant if required, are a compact 117 x 56 x 12.7mm in size, with a height above board of 10.9mm.
