The Power Integrations TOP259EG is a Flyback offline switcher from the TOPSwitch®-HX series with an integrated switch and galvanically isolated output. It delivers up to 238 W with a 700V breakdown rating, 66kHz/132kHz switching, and 78% maximum duty cycle. Housed in a 7-SSIP package, it includes current limiting, over temperature, and over voltage protection across a -40°C to 150°C junction range.
- Integrated switch reduces external component count in isolated Flyback designs.
- 700V breakdown rating supports robust offline operation.
- 238 W power capability suits medium-to-high power supplies.
- Dual 66kHz/132kHz frequency options aid design flexibility.
- Built-in current limiting, over temperature, and over voltage protection improve reliability.
