Vicor announces the addition of six mid-power Micro DC-DC converters to the 48Vdc input family: a 50W model at 3.3 Vout and 75W models at 12, 15, 24, 28, and 48Vout. The modules — which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) — are appropriate for power system applications in distributed power, medical, ATE, communications, defence, and aerospace.

With these new models, the 48Vin Micros family now comprises 16 models with output voltages from 2 to 48Vdc and power levels from 50 to 150W. The converters operate from 48V nominal input, with an input range of 36V to 75V. 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.

These mid-power products provide designers, who do not require the
full-power capability of the Micro module, with a wider range of options that will make their designs more cost effective. 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.

Available as RoHS compliant models if required, the modules are a compact 57.9 x 36.8 x 12.7mm in size with a height above board of 10.9mm.
