UCC28056: Brown-in/Brown-out

Part Number: UCC28056

Hi,

Good day. I hope you are well.

Our customer wants to know if the UCC28056 has a brown-in function, How about the brown-out? They want to design a brown-out circuit, but cannot find any information at the datasheet about this. They can see brown-in only.

If this has no brown-out, we would appreciate if you could suggest a FFF for this device.

Thank you and stay safe.

Regards,

Cedrick

    Hi Cedrick,

    thanks for your interest in UCC28056.

    You are correct, there is brown in function but no brown out in UCC28056.

    If custermer wants have brown out, I suggest maybe downstream controller can do this,like most of Flyback controller.

    Also there is a TIDA-010038 reference design includes the external brown out circuit on UCC28056. The link to the schematic is:
