The Power Integrations INN3479C-TL is an isolated Flyback offline switcher from the InnoSwitch3-MX family with an integrated 750V switch, delivering up to 75W. It switches at 25kHz and includes current limiting, over temperature, over voltage, and short circuit protection. Housed in a 24-PowerSMD module with 17 leads and rated for -40°C to 105°C, it suits compact isolated power supplies.
- Isolated Flyback topology provides galvanic isolation for safety-critical offline supplies.
- Integrated 750V switch supports offline operation with fewer external parts.
- Supports up to 75W output power.
- Comprehensive protection set including short circuit protection improves reliability.
- 24-PowerSMD module package simplifies thermal and layout design.
