UCC256301: about how to design for LLC transformer and primary side circuit

Hello E2E,

I do like to suggest the TI's LLC device for 250-W output AC/DC power supply to our customers.
I will suggest following products;
  - UCC25630x  LLC-controller
  - UCC28056  PFC-controller
  - UCC24624  SR-controller
I have never designed LLC-converter.
Does TI have a design manual for LLC transformer?

Best regards,
ACGUY
