Product Name: DC-DC converters have low-noise zero-current/voltage switching
Product Description
Vicor has added eight mid-power Maxi DC-DC converters to its 24 Vdc input family: a 3.3 Vout, 200 W model and 300 W models at 5, 12, 15, 24, 28, 36, and 48 Vout. The modules – which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) topology – are appropriate for industrial or process control, distributed power, medical, ATE, communications, defence, and aerospace applications. With switching frequencies up to 1 MHz, the 24 Vdc family provides rapid transient response well suited for RF applications.
The new products provide designers who do not need the full-power capability of a 24V Maxi module with a mid-power option, with all of the functionality and configurability of the high power models. In addition, low-noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements.
The modules, which are available in RoHS compliant models, are a compact 117 x 56 x 12.7mm in size, with a height above board of 10.9mm.
With these new models, the 24Vin Maxi family now comprises 16 models with output voltages from 3.3 to 48Vdc and power levels from 200 to 400W. The converters operate from 24V nominal input, with an input range of 18V to 36V. Efficiencies range up to 88% for the higher output voltages. These models are available in five different environmental grades, with six different pin options and three choices of baseplate. They can be configured in any combination in Vicor’s Custom Module Design System at www.vicoreurope.com.
Vicor’s comprehensive line of power solutions includes modular, high-density AC-DC and DC-DC modules and accessory components, fully configurable AC-DC and DC-DC power supplies, and complete custom power systems.
