... Zero Cross Switching Circuit Operating Principles • The LC75384NE-R/NW include functions for switching the place where the zero cross comparator operates and thus allows applications to select the optimal detection location for the block for which the control data is updated. Basically, switching noise will be minimized if the signal immediately following the block for which the control data is updated is input to the zero cross comparator ...
