The flyback transformer plays a crucial role in the performance of the green-mode controller. Considerations must be given to adequate coupling for the bias windings, minimizing leakage inductance, and minimizing audible noise. All of these criteria can easily be met with proper transformer design from the start. Once the Design Calculator spreadsheet, (TI Literature Number SLVC104) , determines the required turns ratio, the following guidelines will enable the user to design a transformer that meets the performance requirements of the converter.
