_____________
Adjusting the Over-Current Limit
ROCx is the resistor used to adjust the over-current trip point. The trip point corresponds to the peak inductor current indicated on
the x-axis of Fig. 21. (Note: The trip point will be higher than expected if the reference board is cool and is being used for short
circuit testing.)
