This design features the UCC28730 flyback controller in conjunction with the UCC24650 Wake-Up monitor to provide CV, CC regulated output with ultra-low stand-by power that exceeds Level VI and CoC Tier 2 specifications for average efficiency and 10% load efficiency. Wake-up signal detection provides fast transient response to large load steps.
Remark-- BOM and test result pdf is added with schematic diagram pdf
