The Power Integrations TOP255YN is an offline flyback switcher from the TOPSwitch®-HX series with an integrated switch and 700V breakdown rating. It delivers up to 81 W with selectable 66kHz or 132kHz switching and a 78% maximum duty cycle, providing galvanically isolated output. Current limiting, over temperature, and over voltage protection are built in, and the TO-220-7 formed-lead package supports operation from -40°C to 150°C junction temperature.
- Integrated switch reduces external component count and simplifies isolated flyback designs.
- 700V breakdown rating provides margin for high-voltage offline input conditions.
- 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 suits demanding thermal environments.
AC-DC Adapters and Chargers
The TOP255YN's 700V breakdown rating and 81 W power capability make it well suited for isolated flyback adapter designs that need to withstand high input voltage stress while delivering regulated output.
Standby and Auxiliary Supplies
With selectable 66kHz or 132kHz switching and a 78% maximum duty cycle, designers can balance transformer size against switching losses in auxiliary power rails.
Industrial Control Power
The -40°C to 150°C junction temperature range supports reliable operation in thermally demanding industrial environments where isolated flyback conversion is required.
Consumer Electronics Power
Integrated switch and built-in current limiting, over temperature, and over voltage protection simplify isolated flyback designs for household electronics.
