Part Number: UCC28810EVM-003

Hi Team,

Do we still have UCC28810EVM-001? Where can I apply it?

If not, does UCC28810EVM-003 can be modified to a single stage Flyback? How to do it?

Thanks.

BRs,

Hi Francis,

I can't see the UCC28810EVM-001 anywhere. For a single-stage PFC flyback example, have a look at PMP10155.

I hope this answers your question.

Hi JCHK,

Customer needs to evaluate it at first.

Hi Francis,

There is no current inventory or restock plans for anything other than the -003 EVM. I can see if we have some lying around.

Hi JCHK,

Thanks, on the other hand, can 003 EVM be modified to a single stage Flyback?

Customer only need to evaluate this device in Flyback circuit.

Hi Francis,

If you want to look at the EVM -003 as a pure flyback, the EVM schematic on page 4 of the EVM guide has notes on how to use it without a boost follower and you use the PFC+ to GND as the load.

Is this what you are trying to do?

Hi JACK,

But in EVM -003, UCC28810D controls the PFC stage, UCC28811D controls the Buck stage and TPS92020D controls the Flyback. PFC+ to GND seems cannot directly control a Flyback.

What customer wants is the circuit figure in UCC 28810 datasheet:

Hi Francis,

This is why I recommended following PMP10155

This seems like it is what your customer would like to do.
