説明

Designed to address the challenges of higher-power isolated conversion, this 75 W solution delivers excellent efficiency while maintaining the simplicity and cost advantages of a flyback topology. By retaining this architecture, the design minimizes overall system cost and complexity compared to alternative higher-power approaches.

Optimized for harsh industrial environments, it ensures low heat dissipation, controlled component stress, and reliable thermal performance, achieving up to 94% peak efficiency. The no optocoupler synchronous flyback architecture further enhances reliability by reducing component count and eliminating common failure points. The result is a robust, space-efficient solution providing stable low-voltage isolation, high efficiency, and long-term reliability in demanding applications.

APPLICATIONS

  • Isolated Telecom
