Part Number:UCC24612
I am using a UCC28740 in combination with UCC24612 in the return leg of secondary side of transformer. I am trying to implement a CM Balanced transformer design but i am not clear as to phasing when my SR is in the return leg. Application note titled "Flyback transformer design considerations for efficiency and EMI" states that special care needs to be taken when using Sr in the return leg while utilizing PSR regulation. Can i get a more clarification on how to properly phase the winding using the suggestions in this note. I will attach an a schematic of an application with PSR and Diode in the positive leg.
