The LNK3694G-TL from Power Integrations is a flyback offline switcher in the LinkSwitch-XT2 series, delivering up to 6 W with a 900V breakdown rating and an integrated power switch. It operates at 66kHz with a 65% maximum duty cycle and provides current limiting, over temperature, and over voltage protection. Housed in an 8-SMD (7 leads) gull-wing package, it is rated for -40°C to 150°C junction temperature.
- High 900V breakdown rating provides margin for high-voltage offline flyback designs.
- Integrated switch reduces external component count and simplifies isolated supply design.
- 6 W output power suits compact auxiliary and bias supplies.
- Built-in current limiting, over temperature, and over voltage protection enhance reliability.
- Wide -40°C to 150°C junction temperature range supports demanding thermal environments.
Compact Offline Power Supplies
The LNK3694G-TL delivers up to 6 W in a flyback topology with a 900V breakdown rating, making it well suited for small isolated AC-DC supplies where high voltage margin is required.
Industrial Auxiliary Bias Supplies
With an operating temperature range of -40°C to 150°C (TJ) and integrated switch, this device supports reliable bias power in industrial equipment operating in demanding thermal environments.
