$750-1500 USD

Paid on delivery
I have an offline flyback converter that functions, but needs some revisions. It's a 300W (250W usage) design with 85VAC to 280VAC input. Goes into a PFC stage, then flyback stage to isolate. Secondary side then has an avg. current mode buck that outputs to a high voltage high power LED array. I need someone to look at the design as-is and see if there are any standouts for UL/FCC approval. Additionally I'd like someone to help optimize and improve the design. Constraints are price and transformer selection. More details will be provided to the freelancers that ask and show that they have an understanding of offline power supply design.
