The ER9.5 Flyback Transformer is designed for compact switching power supplies and isolated DC-DC converter systems requiring stable high-frequency operation and efficient energy transfer. Based on the ER-core magnetic structure, it delivers reliable electrical performance while supporting compact PCB integration.
Its compact size and optimized winding structure make it suitable for modern miniaturized electronic devices where space efficiency and stable output performance are essential.
Compared with larger ER-series transformers, the ER9.5 focuses on low-power and compact electronic applications while maintaining reliable isolation and high-frequency conversion capability.
Customized turns ratios, insulation structures, winding configurations, and pin layouts are available according to customer requirements.
Characteristics:
This solution enables simple and fast design integration while reducing the number of external components and minimizing PCB footprint, making it a highly cost-effective choice. It eliminates the need for an optocoupler, ensuring stable and reliable long-term voltage regulation without aging-related performance degradation. Additionally, it allows shared external components across different output voltages, significantly simplifying custom power supply design. With a standardized reference circuit, only the transformer and two feedback components need to be adjusted, providing greater flexibility and efficiency in product development.
