375 Vin DC-DC converter module line gets extended
30 May 2007
Power Electronics / Power Management
Vicor has added eight mid-power Mini DC-DC converters to its 375 V d.c. input family: a 100 W model at 3,3 Vout; 150 W model at 5 Vout; and 200 W models at 12, 15, 24, 28, 36, and 48 Vout. These half-brick modules - which incorporate Vicor's patented low-noise zero-current and zero-voltage switching (ZCS/ZVS) - can be used in a variety of applications, including off-line systems with autoranging or PFC front ends, industrial and process control, distributed power, medical, ATE, communications, defence, and aerospace.
Low-noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency-conducted emissions requirements, according to Vicor.
The company's 375 Vin Mini family now comprises 17 models with output voltages spanning 2 to 48 V d.c. and power levels from 100 to 300 W. The converters operate from 375 V nominal input, with an input range of 250 V to 425 V. Efficiencies range up to 89% for the higher output voltages.
The models are available in five different environmental grades, with six different pin options and three baseplate options. They can also be configured in any combination using Vicor PowerBench, an intelligent online design system that allows a customer to configure a vast array of custom module designs on-line, and verify them in realtime.
The RoHS modules are a compact 57,9 x 55,9 x 12,7 mm in size with a height above board of 10,9 mm.
