The Power Integrations TOP270VG is a TOPSwitch-JX offline switcher IC integrating the power switch for isolated Flyback designs up to 55 W. It offers a 725V breakdown rating, 78% maximum duty cycle, and selectable 66kHz/132kHz switching with frequency control. Housed in a 12-SDIP package with exposed pad, it includes current limiting, over load, over temperature, over voltage, and short circuit protection across a -40°C ~ 150°C junction range.
- Integrated switch simplifies isolated Flyback designs and cuts external parts.
- 725V breakdown rating supports robust offline operation.
- Selectable 66kHz/132kHz frequency control aids transformer optimization.
- Comprehensive fault protection improves reliability.
- Wide -40°C ~ 150°C junction range suits demanding environments.
Compact AC-DC Adapters
The integrated switch and 725V breakdown rating make the TOP270VG well suited to isolated Flyback adapters up to 55 W, reducing external component count.
Industrial Auxiliary Supplies
With a -40°C ~ 150°C junction temperature range, this device supports isolated bias and auxiliary rails in demanding environments.
Consumer Power Supplies
Selectable 66kHz/132kHz frequency control lets designers balance transformer size and switching behavior in isolated Flyback designs.
Standby and Housekeeping Rails
Comprehensive fault protection including over load, over voltage, and short circuit helps safeguard isolated low-power rails.
