Jakub Plucinski

Part Number: AMC1100
Other Parts Discussed in Thread: TIDA-01094,

Hello, is there any available reference design for capacitive-drop power supply of AMC's 1100 primary side, as described in SLAA552?

I would like to see the layout for this kind of suggested suppply.

Best regards, Jakub.

Hi Jacob,

Welcome to our e2e forum! I'm not aware of any specific reference designs that include the AMC1100 with a cap drop supply, but you can certainly review TIDA-01550 which provides a cap-drop supply to a digital isolator and TIDA-01094 which provides a cap-drop supply to the AMC1304. For the AMC1100, you would need to use the voltage regulator option described in the documents.
