The Power Integrations TOP258PN is a TOPSwitch®-HX flyback offline switcher integrating a 700V switch in an 8-DIP package. It delivers up to 48 W at 66kHz with a 78% maximum duty cycle and galvanically isolated output. Current limiting, over temperature, and over voltage protection combined with a -40°C to 150°C junction temperature range make it a robust choice for isolated offline power supplies.
- Integrated 700V switch simplifies isolated flyback designs and reduces external parts.
- 48 W output power at 66kHz supports compact offline supplies.
- 78% maximum duty cycle enables efficient transformer utilization.
- Current limiting, over temperature, and over voltage protection improve system safety.
- -40°C to 150°C junction temperature range supports demanding environments.
