PRODUCTION DATA.
AUX is a high-current gate-drive output for the auxiliary switch to implement the active-clamp operation for the power stage. The auxiliary output (AUX) of the UCC2897A drives a P-channel device as the clamp switch therefore it requires an active-low operation (the switch is ON when the output is low).
