The LNK3294P from Power Integrations (LinkSwitch-TN2 series) is a non-isolated offline switcher supporting buck, buck-boost, and flyback topologies with an integrated 900V power switch. It operates at 66 kHz with 68% maximum duty cycle and includes current limiting, open loop, over load, over temperature, over voltage, and short circuit protection plus soft start. Packaged in 8-DIP, it suits compact non-isolated offline supplies.
- 900V integrated switch provides high voltage margin for offline designs.
- Multi-topology support (buck, buck-boost, flyback) adds design flexibility.
- Soft start and EN control simplify regulation and startup.
- Broad fault protection (OCP, OLP, OTP, OVP, SCP, open loop) improves reliability.
- Wide -40°C to 150°C junction range suits demanding environments.
Non-Isolated Buck Supplies
The LNK3294P's 900V integrated switch and buck topology suit direct-coupled step-down offline supplies with high voltage margin.
Buck-Boost Auxiliary Rails
Supporting buck-boost operation, it handles step-up/down non-isolated rails for control and bias circuits.
Appliance Power Boards
Operating from -40°C to 150°C junction temperature, it meets the thermal needs of appliance control electronics.
Low-Power Flyback Designs
When isolation is required, the flyback configuration provides flexibility, with soft start and EN control easing design.
