Part Number: UCD3138
Other Parts Discussed in Thread: UCC24624, UCD7138

Hi Team,

My customer wants to found the solution bridgeless PFC+LLC+SR controller.

Is there a recommended combination?

The spec as the below,

Vin=100Vac for output 56V, 24A / 1333W

Vin=230Vac for output 56V, 30A / 1700W

Does UCD3138+UCC25640X+UCC24624 can reach this SPEC?

If the customer didn't want to use the UCD3138, there have another CCM PFC can be replaced? Is TI has any design for reference, thanks.

Best regards

Rock
