EE20/10/6 Offline Transformers Offline Flyback Transformers
This product features a user-friendly design for straightforward implementation, requires a minimal number of external components, and has a small PCB footprint to save board space, offering an economical solution with low overall cost. It adopts an optocoupler-free design, delivers reliable long-term voltage regulation performance with no performance drift or aging over time, and uses identical external parts for different output voltages. Custom power supply design is easy thanks to the standard circuit, requiring only a transformer change and two feedback loop components. It is commonly used in isolated power design, sensor interfaces, isolated telecom converters, and Power over Ethernet (PoE) applications.
