Good day Team
I am searching for a AC-DC design that has a very high probability of working.
I was guided to one of the competitor sites and chose a design fitting my requirements. They also have a online design system. After choosing the chip and design the design suddenly disappeared from the design center. The design also does not work. I even had a custom Transformer build as per the design specs.
Due to this my project is being delayed and I cannot afford this again.
I have been looking at the current forum, WEBENCH and the reference designs. There are just so many. I will just guess that TI will create new control chips with improved features.
My design is an wide input AC-DC converter that will drive a battery charging circuit as well as a power bypass to drive the rest of the circuit. As I understand Flyback topology is the best and I just think the secondary feedback is the best. The circuit has to be Isolated. I do not need Automotive Spec.
If I can have the minimum Output ripple it will be great.
Input: AC - 85V Ac - 265V Ac
Output: 20-22 V Dc
Output Current: Max 4A
In WEBENCH there are 3 different families listed: LM, UC and UCC. Which family is the latest chip design and which one is the best to use
There are just so many options. Can you give me any sort of guidance?
