UCC21750-Q1: Analog input (AIN) if unused, then pull down required or not?

Part Number: UCC21750-Q1

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
