The Vicor VDAC (Vicor Design Assistance Computer) is a patented system that enables Vicor's customers to specify on-line, and verify in real time, the performance and attributes of Maxi, Mini and Micro DC-DC converters. Designs are downloaded directly into Vicor's computer-integrated manufacturing (CIM).

Electrical performance is obviously a fundamental
consideration to designers using component power modules. In this mini-seminar,
the emphasis is on describing standard features – e.g., undervoltage
lockout, overvoltage protection – associated with Maxi, Mini and Micro
DC-DC converters.
