I was using L4985A in my boost converter circuit. I was observing abnormal current spikes in input current waveform and audible noise is coming in no load condition itself, same in load current.Current spike coming every few seconds?

Boosting operation starts at 80Vac.It is working fine and voltage is boosted to 400Vdc as per design. Please refer the attached Input current current and duty waveform in no load condition, schematics.
