The Power Integrations LNK3307D-TL is a multi-topology offline switcher from the LinkSwitch®-TNZ series, supporting Buck, Buck-Boost, and Flyback configurations with isolated output. It integrates a 725V switch, delivers up to 12 W, and operates at 66kHz with 69% maximum duty cycle. Protections include current limiting, open loop, over temperature, over voltage, and short circuit, with enable and soft start control in an 8-SOIC package rated to 150°C junction temperature.
- Multi-topology flexibility (Buck, Buck-Boost, Flyback) simplifies design reuse.
- Integrated 725V switch reduces external components and BOM cost.
- Comprehensive fault protection (open loop, over voltage, short circuit) improves reliability.
- Soft start and enable control support stable, controllable startup.
- 150°C junction temperature rating enables use in thermally demanding designs.
