Product Overview

The EP5 flyback transformer is a compact high-frequency magnetic component designed for low-power DC/DC conversion and isolated power supply applications. With its ultra-small footprint and optimized magnetic structure, it is ideal for space-constrained designs such as portable electronics and embedded systems.

Operating in high-frequency switching environments, the transformer enables efficient energy transfer while significantly reducing the overall size compared to traditional low-frequency transformers.

Design Flexibility & Customization

The EP5 transformer supports full customization for different circuit requirements:

Custom turns ratio and output voltage design
Multi-output winding configurations
SMD or through-hole mounting options
Optimization for specific controller ICs

Its flexible design makes it suitable for both standard and application-specific power solutions.

Application Scenarios

The EP5 transformer is widely used in compact and low-power electronic systems:

DC/DC converter modules
IoT devices and smart sensors
Portable and wearable electronics
Auxiliary power supplies in industrial control systems
Communication interface modules
