Mid-Power 48V In Micro DC/DC Converters From Vicor

(Product News, 31 Oct 2006)

Vicor has added six mid-power Micro DC/DC converters to its 48V DC input family: a 50W model at 3.3 Vout and 75W models at 12, 15, 24, 28, and 48 Vout. The modules — which incorporate the company's 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. The converters operate from 48V nominal input, with an input range of 36V to 75V. Efficiencies range up to 89 percent for the higher output voltages. These models are available in five different environmental grades, with six different pin options and three baseplate options. The modules, which are optionally available in RoHS compliant models, are a compact 2.28 x 1.45 x 0.5-inch (57.9 x 36.8 x 12.7 mm) in size with a height above board of 0.43 inch (10.9 mm). The mid-power Micros are priced from $48 in quantities of 1,000.
