This offline flyback reference design uses the UCC28740 controller to generate an isolated output (12 V at 1 A) from a wide AC input (156 VAC - 440 VAC). The design was developed to be resistant to large magnetic fields (200mT) near the transformer. The transformer, the frequency and modulation modes were optimized for improved magnetic resistance.
