The Power Integrations TOP268VG is a flyback offline switcher from the TOPSwitch®-JX series with an integrated power switch and 725V breakdown voltage. It delivers up to 48W at 66kHz or 132kHz switching with 78% max duty cycle. Protections include current limiting, over load, over temperature, over voltage, and short circuit. Housed in a 12-SDIP package rated -40°C to 150°C.
- Integrated switch and 725V breakdown simplify isolated flyback designs.
- Up to 48W output suits mid-power applications.
- Dual 66kHz/132kHz frequencies with frequency control aid design flexibility.
- Comprehensive protections (OL, OT, OV, SC, current limiting) boost reliability.
- -40°C to 150°C junction range suits harsh environments.
