The Power Integrations LNK3312D-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 3 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-Power Bias Supplies
The LNK3312D-TL delivers up to 3 W in Buck, Buck-Boost, or Flyback configurations, ideal for isolated bias rails.
Standby and Auxiliary Power
66kHz switching and 725V breakdown support compact offline auxiliary supplies with soft start.
Smart Meter and IoT Power
EN control and soft start simplify low-power isolated designs for connected devices.
