CSD86330Q3D: May we direct use CSD86330Q3D to replace FDMS3664S?

Part Number: CSD86330Q3D

Hi Sir 

Sorry for i am not familiar power stage ic, May we direct use CSD86330Q3D to replace FDMS3664S?

or other parts we can suggest customer?


  • Bogey,
    In theory yes, but I would be cautioned that the TI power block only has 25V BVDSS so depending on your input voltage and the amount of ringing you anticipate, you may want to use a 30V device/power block like the Fairchild dual-FET.

    You may want to play around with the NexFET Buck Converter selection tool we have to see what the correct replacement would be for input conditions.
