The TOP254EN from Power Integrations is a flyback offline switcher in the TOPSwitch®-HX family, delivering up to 62 W with a 700V integrated MOSFET. It offers galvanically isolated output, selectable 66kHz/132kHz switching, and 78% maximum duty cycle. Built-in current limiting, over temperature, and over voltage protection support reliable AC-DC designs in a 7-SSIP package.
- Integrated 700V MOSFET reduces external components and simplifies isolated flyback design.
- Up to 62 W output supports a wide range of AC-DC applications.
- Selectable 66kHz/132kHz switching frequency aids transformer and EMI optimization.
- Comprehensive protection (current limiting, over temperature, over voltage) improves reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
