  • Hi Rajendra,

    I see "LOAD & LINE REGULATION > 5% " in you attached file , usually , the specification requires load and line regulation less than X% , so can you clarify that is this is a mistake or not ?  and since it's a multiple design , does 5% regulation for all of outputs or just main output , any requirement for cross regulation .

    UCC28700 is a PSR controller , it can meet +/-5% load and line regulation . if your requirement is higher than this , you can consider  SSR controller such as UCC28740 and UCC28742 .

    I also see the input voltage is up to 480Vac , if you use UCC28700 , the VS pin need additional diode and Zener to prevent the current out of it exceed 1.0mA.

    See as below :
