8.4.2 Conduction Mode

Conduction mode occurs when the gate driver is enabled. There are three regions of operating during conduction mode based on the ANODE to CATHODE voltage of the LM74700-EP. Each of the three modes is described in the Regulated Condution Mode, Full Conduction Mode and Reverse Current Protection Mode sections.
