Vicor Introduces New Mid-Power 48 Vin Micro Modules

August 02, 2006 by Jeff Shepard

Vicor Corp. announced the addition of six mid-power Micro dc-dc converters to the 48Vdc input family: a 50W model at 3.3Vout 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, 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 48Vin Micro 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 36 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 available on the company's website.

The modules, which are optionally available in RoHS compliant models, are a compact 2.28 x 1.45 x 0.5 inch in size with a height above board of 0.43 inch. The new mid-power Micros are available from stock to 6 weeks leadtimes and are priced from $48 in quantities of 1000.

"These mid-power Micros provide designers, who don't require the full-power capability of the Micro module, with a wider range of options that will make their designs more cost effective," said Robert Marchetti, Manager, Product Marketing.
