High-Efficiency Flyback Transformer | 0.5W - 150W Power Range
Product Overview Highly reliable Flyback Transformers engineered for optimal energy storage and transfer in Switch-Mode Power Supplies (SMPS). Acting as coupled inductors, these transformers store energy during the switching transistor’s “on” time and release it to the load during the “off” time. Designed with dedicated Primary, Auxiliary (for IC bias), and Secondary windings, they utilize versatile core geometries like EE, ETD, and EFD to deliver excellent magnetic coupling and compact footprints.
Power Rating & Core Size Guide | Core Size | Estimated Power Rating | | :— | :— | | 5mm – 20mm | 0.5 W – 10 W | | 20mm – 30mm | 10 W – 50 W | | 30mm – 40mm | 50 W – 150 W |
Applications Essential for AC-DC wall adapters, USB fast chargers (PD/QC), LED lighting drivers, standby power supplies, PoE (Power over Ethernet) devices, and consumer electronics requiring reliable, low-cost isolated power conversion.
