EP10 Flyback Transformer

The EP10 series flyback transformer is optimized for simplified isolated power supply design. Through its integrated architecture and optocoupler-free feedback scheme, it delivers a one-stop solution that balances cost, space, and reliability. Power supply designs with different output voltages can be realized simply by replacing the transformer and a small number of feedback components, which significantly shortens product development cycles while ensuring long-term stable voltage control performance.
