Vicor Corp. in Andover, Mass., is adding nine mid-power mini DC-DC converters to the 24-volt DC-input family: a 100-watt model at 3.3 volts, 150-watt models at 5, 12, 15, 24, 28, 36, and 48 volts. A 200-watt model at a new standard 36-volt output has also been added. The modules, which incorporate Vicor’s low-noise zero-current and zero-voltage switching (ZCS/ZVS), can be used in applications such as industrial or process control, distributed power, medical, ATE, communications, defense, and aerospace. Low-noise ZCS/ZVS reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements. With these new models, the 24-volt Mini family now comprises 16 models with output voltages from 3.3- to 48-volts and power levels from 100 to 200-watts. The converters operate from 24-volt nominal input, with an input range of 18 to 36 volts. Efficiencies range to as much as 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. They can be configured in any combination in Vicor’s Custom Module Design System at www.vicorpower.com.
