The LNK564DN-TL from Power Integrations is a LinkSwitch®-LP Flyback offline switcher delivering up to 3W with galvanically isolated output. It integrates the power switch and operates at 100kHz with a 70% maximum duty cycle and 700V breakdown rating. Current limiting, open loop, over temperature, and short circuit protection are built in. Housed in an 8-SOIC package with a -40°C to 150°C junction range, it suits compact isolated bias and adapter designs.
- Flyback topology with isolated output provides galvanic separation for safety-critical designs.
- Integrated power switch reduces external component count and board space.
- 700V breakdown voltage offers robust margin for offline mains operation.
- Built-in current limiting, open loop, over temperature, and short circuit protection enhance reliability.
- Compact 8-SOIC package with -40°C to 150°C junction range suits space-constrained, thermally demanding applications.
Isolated Low-Power Bias Supplies
The LNK564DN-TL's Flyback topology and isolated output make it ideal for generating galvanically isolated bias rails in systems that require safety separation between mains and low-voltage circuitry.
Chargers and Adapters
With a 3W power rating, integrated switch, and 100kHz switching frequency, this device suits compact isolated chargers and small adapters where a minimal external component count is essential.
Standby and Housekeeping Power
Flyback isolation combined with current limiting, open loop, over temperature, and short circuit protection supports reliable standby power stages in appliances and consumer electronics.
Industrial Control Isolation
