For the LM74700-EP to operate in regulated conduction mode, the gate driver must be enabled as described in the Gate Driver section, and the current from source to drain of the external MOSFET must be within the range to result in an ANODE to CATHODE voltage drop of –11 mV to 50 mV. During forward regulation mode, the ANODE to CATHODE voltage is regulated to 20 mV by adjusting the GATE to ANODE voltage. This closed loop regulation scheme enables graceful turn off of the MOSFET at very light loads and ensures zero DC reverse current flow.
