For UCC21750-Q1, Analog input (AIN) & Analog PWM output if unused, then pull down required or not?
Or should only be grounded by capacitor? If yes, 100nF is sufficient?

Hi Abhishek,
Thanks for your interest in UCC21750-Q1 device. The AIN pin [input pin] needs to be tied to COM if unused - so that its not picking up the switching noise. The APWM [Output pin] needs to be left floating if unused.
Hope it answers your question.
Thanks
