Dear TI experts,

    Hi Chase,

    Overall, I think this schematic looks good. We do recommend using 100nF and 1uF capacitors for both high-side and low-side power supplies with the smaller capacitor closer to the device as shown below. 

    Also, please make sure the customer is using separate grounds for the high-side and low-side of the device. Let me know if there are any more questions!

    Best regards,

    Eva

    Hi Chase,

    Can you please comment on why the wide-body package AMC1411-Q1 was chosen for this application? 

    We often see the AMC1311B-Q1, with smaller package and lower isolation ratings used for 400V systems.
