UCC28180: The UCC28180 driver has a step at low level,

Part Number: UCC28180

Dear

   The UCC28180 driver has a step at low level, with an input of 90Vac. When the output is unloaded, the PFC driver has a step at low level, but there is no step at high voltage input or heavy load. Can you help analyze that direct drive does not require transistor discharge to avoid this phenomenon
