The TOP271VG from Power Integrations is an offline flyback switcher with an integrated power switch rated to 725 V breakdown. It delivers up to 59 W with a 78% maximum duty cycle and selectable 66 kHz or 132 kHz switching frequency with frequency control. Comprehensive protection includes current limiting, over load, over temperature, over voltage, and short circuit. It operates across a -40°C to 150°C junction temperature range in a 12-SDIP package.
- Integrated 725 V switch reduces external component count in isolated flyback designs.
- Selectable 66 kHz / 132 kHz frequency with frequency control optimizes transformer and EMI trade-offs.
- Comprehensive fault protection (over load, over voltage, short circuit, over temperature) improves reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
- 59 W output supports a range of offline power applications.
