The Power Integrations LNK302PN is a non-isolated offline switcher from the LinkSwitch®-TN series supporting Buck, Buck-Boost, and Flyback topologies. It integrates the power switch with a 700V breakdown rating and operates at 66kHz with a 69% maximum duty cycle. Built-in current limiting, open loop, over temperature, and short circuit protection ensure safe operation in an 8-DIP package rated for -40°C to 150°C junction temperatures.
- Multi-topology flexibility (Buck, Buck-Boost, Flyback) in a non-isolated, direct-coupled design.
- Integrated switch and 700V breakdown rating reduce external parts and simplify offline designs.
- 66kHz switching frequency balances efficiency and compact magnetics.
- Protection suite including current limiting, open loop, over temperature, and short circuit improves reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
Non-Isolated Offline Power
The LNK302PN is a non-isolated offline switcher from the LinkSwitch®-TN series supporting Buck, Buck-Boost, and Flyback topologies, suited for direct-coupled low-power supplies.
Appliance Control Boards
With a 700V breakdown rating and integrated switch, it handles offline input while reducing external component count for compact control electronics.
Buck and Buck-Boost Rails
