The TOP258EN from Power Integrations is a flyback offline switcher in the TOPSwitch®-HX series, delivering up to 195 W with a 700V integrated power switch. It offers selectable 66kHz or 132kHz switching, 78% maximum duty cycle, and galvanically isolated output. Built-in current limiting, over temperature, and over voltage protection support reliable operation from -40°C to 150°C junction temperature in a 7-SSIP package.
- Integrated 700V power switch reduces external component count and simplifies flyback design.
- Selectable 66kHz/132kHz switching frequency lets designers optimize transformer size versus efficiency.
- Up to 195 W output power supports medium-to-high power offline supplies.
- Comprehensive protection (current limiting, over temperature, over voltage) improves reliability.
- Wide -40°C to 150°C junction temperature range suits demanding thermal environments.
AC-DC Power Adapters
The TOP258EN's 700V breakdown rating and integrated switch make it well suited for offline flyback adapters requiring up to 195 W. The 66kHz/132kHz selectable frequency allows designers to balance transformer size against switching losses.
Industrial Power Supplies
With a junction temperature range of -40°C to 150°C, this flyback switcher supports industrial supplies that must operate reliably across wide thermal conditions. Built-in current limiting and over temperature protection safeguard the supply under fault conditions.
Consumer Electronics Power
Galvanically isolated flyback topology provides the safety isolation required for consumer AC-DC supplies. The integrated MOSFET reduces BOM count, helping compact designs meet space constraints.
Standby and Auxiliary Rails
The 78% maximum duty cycle and dual frequency options give flexibility for auxiliary power rails in larger systems, where a robust isolated flyback stage is needed.
