200kHz > Fsw < 1MHz according to data sheet, but EMC problems fixed by reducing Fsw. Initial trials satis but what are the reliability issues arising?
UKFAE: I heard back from the designer on your request
I think it would be fine for ADuM4070 to operate at 120kHz. The internal circuit will support this low switching frequency. However, the customer…
Thank you, much appreciated - David
