The LNK564DG-TL from Power Integrations is a LinkSwitch®-LP Flyback offline switcher providing up to 3W with galvanically isolated output. It integrates the power switch and runs at 100kHz with a 70% maximum duty cycle and 700V breakdown rating. Current limiting, open loop, over temperature, and short circuit protection are integrated. The 8-SOIC package and -40°C to 150°C junction range make it well suited to compact isolated bias and adapter designs.
- Isolated Flyback topology provides galvanic separation for safety-critical designs.
- Integrated power switch minimizes external components and board footprint.
- 700V breakdown voltage delivers robust margin for offline operation.
- Comprehensive fault protection (current limiting, open loop, over temperature, short circuit) improves reliability.
- Compact 8-SOIC package with -40°C to 150°C junction range supports demanding thermal environments.
Isolated Auxiliary Power
The LNK564DG-TL's Flyback topology and isolated output deliver galvanically separated power for auxiliary rails requiring safety isolation from the mains.
Compact Adapters and Chargers
A 3W rating, integrated switch, and 100kHz switching frequency make this device suitable for small isolated adapters and chargers with minimal external parts.
Standby Power Stages
Flyback isolation plus current limiting, open loop, over temperature, and short circuit protection support dependable standby and housekeeping supplies.
Industrial Isolated Modules
The -40°C to 150°C junction range and isolated Flyback design fit industrial control modules needing a small isolated bias supply.
Sensor and Metering Electronics
An isolated 3W Flyback stage safely powers sensor and metering front-ends referenced to mains-connected systems.
