The Power Integrations TOP270KG-TL is an isolated flyback switcher from the TOPSwitch-JX series with an integrated power switch. It offers a 725V breakdown rating, 78% maximum duty cycle, 66kHz and 132kHz switching with frequency control, and up to 91 W output. Current limiting, over load, over temperature, over voltage, and short circuit protection support operation from -40°C to 150°C in a 12-BESOP exposed-pad package.
- Integrated power switch simplifies flyback design and reduces component count.
- 725V breakdown rating supports robust offline operation.
- Up to 91 W output for higher-power isolated supplies.
- Selectable 66kHz/132kHz switching with frequency control.
- Comprehensive protection and -40°C to 150°C range for demanding environments.
