The LM5067EVAL evaluation board provides the design engineer with a fully functional hot swap controller board designed for negative voltage systems. This board contains an LM5067-2, the auto restart version of this IC. This application note describes the various functions of the board, how to test & evaluate it, and how to change the components for a specific application. The LM5067 data sheet is available from www.ti.com.
