The Power Integrations TOP258EG is a TOPSwitch®-HX flyback offline switcher with an integrated 700V switch, delivering up to 195W in an isolated topology. It offers 66kHz and 132kHz switching frequencies and a 78% maximum duty cycle. Current limiting, over temperature, and over voltage protection combine with a -40°C to 150°C junction range in a 7-SSIP package.
- Integrated 700V switch reduces external component count in flyback designs.
- 195W power capability supports higher-power isolated supplies.
- Dual 66kHz/132kHz frequencies enable transformer and efficiency optimization.
- Comprehensive protection: current limiting, over temperature, over voltage.
- -40°C to 150°C junction range suits demanding thermal environments.
