The Power Integrations TOP258YN is an isolated flyback switcher from the TOPSwitch-HX series with an integrated power switch. It offers a 700V breakdown rating, 78% maximum duty cycle, 66kHz and 132kHz switching, and up to 195 W output. Current limiting, over temperature, and over voltage protection support operation from -40°C to 150°C in a TO-220-7 formed-lead package.
- Integrated power switch simplifies flyback design and reduces component count.
- Up to 195 W output for high-power isolated supplies.
- 700V breakdown rating supports robust offline operation.
- Selectable 66kHz/132kHz switching for design flexibility.
- -40°C to 150°C range and TO-220-7 package for demanding assemblies.
High-Power Isolated Flyback Supplies
The TOP258YN delivers up to 195 W in an isolated flyback configuration with an integrated switch and 700V breakdown rating, suited to high-power offline AC-DC designs.
Dual-Frequency Flexibility
66kHz and 132kHz switching options let designers balance transformer size against switching losses.
