The VI-221-CW is part of the VI-200 family from Vicor, a well-established series of component-level DC-DC converters designed for high-performance power conversion applications. With more than 14 million units sold, the VI-200 platform is widely recognized for its zero-current-switching (ZCS) architecture, which improves efficiency, reduces noise, and enhances overall system reliability.
Operating at switching frequencies up to 2MHz, the VI-200 series delivers strong performance in terms of power density, thermal stability, and electrical efficiency. The architecture is designed to support scalable power solutions, including the use of booster modules (VI-Bxx), which allow users to build synchronous arrays capable of delivering several kilowatts of output power.
The VI-221-CW model operates with an input voltage range of 36V (21V to 56V) and provides a regulated 12V output at 100W power. It is designed for through-hole mounting and operates within a temperature range of -10°C to 85°C, making it suitable for a wide range of industrial and electronic applications.
In terms of physical dimensions, the module measures 116.80 mm in length, 61.0 mm in width, and 12.7 mm in height. It offers an efficiency rating of approximately 88% and comes in a full-brick package format.
Key features of the VI-221-CW include remote sense functionality, current limiting, logic disable control, wide-range output adjustment, zero-current-switching (ZCS) power architecture, low-noise FM control, and CE certification. These characteristics make it suitable for industrial power systems, communication equipment, embedded electronics, and other high-reliability applications requiring stable DC-DC conversion.
