Adjusting the Over-Current Limit
R7 & R8 are the resistors used to adjust the over-current trip point. The trip point is a function of the controller and
corresponds to 165% of the output current indicated on the x-axis of Fig. 6. For example, selecting a resistance of 1.5K
at each phase will set the trip point to 165% of 15A, or 24.75A. The trip point for each phase on the demoboard is currently
set to 165% of 20A, or 33A.
