The Power Integrations TOP256EG is a Flyback offline switcher from the TOPSwitch®-HX series with an integrated power switch and 700V breakdown rating. It delivers up to 119 W with selectable 66kHz or 132kHz switching frequency and 78% maximum duty cycle. Built-in current limiting, over temperature, and over voltage protection support robust isolated AC-DC designs across a -40°C to 150°C junction temperature range in a 7-SSIP package.
- Integrated power switch reduces external component count and simplifies isolated Flyback design.
- 700V breakdown rating provides ample margin for offline AC-DC operation.
- Selectable 66kHz/132kHz frequency lets designers optimize transformer size versus switching losses.
- Built-in current limiting, over temperature, and over voltage protection enhance reliability.
- Wide -40°C to 150°C junction temperature range supports demanding thermal environments.
