Other Parts Discussed in Thread: UCC25600EVM, UCC25600

Hi,

I need to design a power supply of about 420W and I want to use as start point the evaluation board based on the reference design EVM note "UCC25600EVM" -sluu361.pdf.

I am not able to find any transformer and output feedback control design calculations in the design guide.

Please let us know is there any design calculations for the transformer and output feedback control design circuitry based on the UCC25600.
