The Power Integrations LNK3304D-TL is a LinkSwitch™-TNZ offline switcher supporting Buck, Buck-Boost, and Flyback topologies with isolated output and an integrated switch. It delivers up to 6 W at 66kHz with a 69% maximum duty cycle, a 725V breakdown rating, and an 18 V start-up threshold. EN and soft start control plus comprehensive fault protection support compact 8-SOIC AC-DC designs.
- Multi-topology flexibility (Buck, Buck-Boost, Flyback) in one device.
- 725V breakdown provides strong offline input margin.
- Integrated switch and soft start simplify low-power designs.
- Open-loop and full fault protection improve reliability.
- -40°C to 150°C junction range for demanding environments.
Low-to-Mid Power Bias Supplies
The LNK3304D-TL delivers up to 6 W in Buck, Buck-Boost, or Flyback configurations for isolated bias rails.
Standby and Auxiliary Power
66kHz switching and 725V breakdown support compact offline auxiliary supplies with soft start.
