Dear Team,

Our customer want to use UCC27524A to do low frequency (50Hz).

Does this one support low frequency operation?

Many Thanks,

Jimmy

Hello Jimmy,

Low frequency operation is usually fine with low-side drivers. I just tried 50Hz on my 524 EVM and it was working fine. Are they driving a FET or a capacitor? I'm just checking because sometimes people want to draw DC current and the drivers don't really support that.

thanks,

Alex M.
