UCC28070: Multiplier settings at DC input

UCC28070: Multiplier settings at DC input

Part Number: UCC28070
Hi,
The other day, when using the UCC28070 with DC input, we received a response
that it is recommended to drop the VINAC pin low at 3.4 mV/us or less.
If I drop it low at 3.4mV or higher and let it continue to row for 1ms, will the multiplier level be set correctly?
Also, is there something going on?
 
Best regards,

    Hi User,

    the 3.4mV/uS is suggested by designer of this controller mostly depends the sampling precise.

    from application view, I would suggest we can follow the suggestion, much higher or much lower than this value should cause a wrong sampling of Vinac Zero crossing signal.

    hope this helps you.
