Part Number: UCC28730 Other Parts Discussed in Thread: UCC24650 , Hello
I designed flyback power supply based on UCC28730D and UCC24650. Design is made in TI WEBENCH designer and prototype was made according to the design.
Everything is checked with SLUC579…
Hi Dhaval,
Thank you for reaching out.
1. There is only a slight difference. For example Rvs1 is 58k as per the formula in datasheet. Whereas the one in excel sheet optimizes based on available resistor values. It is there in a sheet titled "LOOKUP TABLES…
