UCC2897A: Shut down during 42V

Dear Team,

This circuit will shut down during 42V running overnight.

Do you have ideas what may cause the circuit shut down?

    Hello,

    I would require some more information about this issue:

    What do you mean by circuit shutdown? does the controller get damaged? is any other component damaged? Would the circuit turn-ON when the PCB temperature returns to room temperature? Is there an air-flow when you leave the circuit running overnight? what is the loading condition?

    What is the specification of the power stage, total output power, input voltage range? 

    Regards,
