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 LM74701-Q1. Each of the three modes is described in the Regulated Conduction Mode, Full Conduction Mode and VDS Clamp Mode sections.
