The TOP265EG from Power Integrations is a TOPSwitch-JX family isolated Flyback offline switcher with an integrated power switch. It delivers up to 81W, features a 725V breakdown voltage, and offers selectable 66kHz or 132kHz switching frequency with 78% maximum duty cycle. Built-in current limiting, over load, over temperature, over voltage, and short circuit protection, plus a -40°C to 150°C junction range, make it well suited to robust isolated AC-DC designs.
- Integrated switch simplifies isolated Flyback designs and reduces external component count.
- Up to 81W output power supports a broad range of adapter and bias supply applications.
- Selectable 66kHz/132kHz frequency lets designers balance transformer size and efficiency.
- 725V breakdown voltage provides margin for universal AC input.
- Comprehensive fault protection and -40°C to 150°C range ensure reliable operation.
