UCC28064A: About using only in single phase

Part Number: UCC28064A
Other Parts Discussed in Thread: UCC28056, UCC28064

Hello.

I have a question about UCC 28064.

I am considering using UCC 28064 as a single.

In that case. How can I handle other PIN related to the PHB terminal and Phase B?
Also, I am planning not to mount the parts of the output part of Phase B.
Is it OK?

Do you have application note?

Thank you.

Hi Masazumi-san,

Thanks for your interest in UCC28064A. It sounds like your customer is looking for a single phase TM PFC. Would UCC28056 satisfy your customer's requirements?

Best Regards,

Hello

thank you for your answer.

UCC28056 is under consideration.
We calculate production line and board revision cost etc. for low quantity system.
And I'm thinking if I use UCC28064 A as a single device and reduce the cost when unifying devices.
Please tell me about the method when using again with UCC28064A single.

Thank you.

Hi Masazumi-san,

UCC28064A will force dual phase mode during startup. I am not able to recommend using UCC28064A as a strictly single phase TM PFC with no second phase populated at this time.
