The evaluation board is designed to faciliatate the evaluation of the performance of Vicor’s mounted
ZVS buck product. Sockets are provided to permit quick probing. Input sockets can be used to place
a bulk capacitor. The evaluation board provides lugs, and bottom layer banana jack footprint for input
and output connections, signal connectors allowing wire, signal test points for easy connection to
standard test equipment, and Kelvin Johnson-Jack for accurate voltage measurements of power nodes.
