The LNK3314D-TL from Power Integrations is a LinkSwitch-TNZ offline switcher IC combining a 725V integrated switch with Buck, Buck-Boost, and Flyback topology support. Delivering up to 6 W at 66kHz with a 69% max duty cycle, it includes soft start, EN control, and comprehensive fault protection in a compact 8-SOIC package.
- Integrated 725V switch reduces external component count and board space.
- Multi-topology support (Buck, Buck-Boost, Flyback) enables both isolated and non-isolated designs.
- Comprehensive fault protection including current limiting, open loop, over temperature, over voltage, and short circuit.
- Wide -40°C to 150°C junction temperature range for demanding environments.
- Soft start and EN control simplify system startup and enable management.
Compact Offline Power Supplies
With a 725V breakdown rating and integrated switch, the LNK3314D-TL suits compact offline supplies up to 6 W. The 66kHz switching frequency and 69% max duty cycle help keep the transformer and output components small.
Isolated Flyback Adapters
In Flyback configuration the device provides galvanically isolated output, ideal for low-power chargers and adapters. Soft start and EN control simplify startup and enable control.
Buck and Buck-Boost Auxiliary Rails
The device also supports Buck and Buck-Boost topologies, enabling simple non-isolated auxiliary bias rails from a rectified mains input.
Harsh-Environment Designs
An operating temperature range of -40°C to 150°C (TJ) supports use in demanding thermal environments, while over temperature and short circuit protection safeguard the system.
