Flyback inductor design

WebThe flyback transformer (or inductor) must be designed to handle the peak stored energy, Ipeak x Ipeak x L / 2. The power source will have to supply the transferred energy plus the parasitic switching and resistive losses of the charging circuit, plus some power allowance for transient conditions. WebUCC28810 LED Flyback Transformer Design Calculations Core Selection: Ferrite material is cost effective and widely used for SMPS. EE cores are widely used for low power designs. For the flyback design, it is desired to keep the peak flux density below 280mT for a flyback design: a 15% margin was given for B max with a result of 240mT. μJ10 − ...
