Overview

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.

Features
  • 156 VAC - 440 VAC input to an isolated output
  • Immune to DC magnetic tampering up to an external magnetic field of 200mT
  • Sendust Core Transformer and low switching frequency improve magnetic resistance
