PMP4530

Hi All,

 There is no current shunt resistor which series into DC output side, how to achieve constant current source in this application? 

 how to design the transformer in PMP4530 application? Can I have to know the calculation for reference? I would like to reference it for following spec design:

 Vin: 96~265Vac, Po: 100W, Io: 0.45A, isolation required. 

 Can i reference this application note?

Regards,

Eric
