The Power Integrations TNY274GN-TL is a Flyback offline switcher from the TinySwitch®-III series with an integrated power switch and isolated output. It offers a 700V breakdown rating and delivers up to 11W at 132kHz with 65% maximum duty cycle. Protection includes current limiting, open loop, over-temperature, over-voltage, and short circuit, with an EN control feature. It is supplied in an 8-SMD (7-lead) gull-wing package rated -40°C to 150°C (TJ).
- Integrated switch and Flyback topology simplify isolated offline supply design.
- 700V breakdown voltage supports mains-connected applications.
- Comprehensive fault protection (open loop, over-voltage, short circuit, over-temperature) improves reliability.
- EN control feature supports efficient regulation.
- Wide -40°C to 150°C (TJ) range for demanding environments.
Isolated Offline Power Supplies
The TNY274GN-TL's Flyback topology and isolated output make it ideal for galvanically isolated AC-DC supplies up to 11W, where the integrated switch and 700V breakdown rating simplify mains-connected designs.
Chargers and Adapters
With 132kHz switching and 65% max duty cycle, the device supports compact adapter designs. Comprehensive protection—current limiting, open loop, over-voltage, over-temperature, and short circuit—improves safety in consumer charging products.
Standby and Auxiliary Supplies
The EN control feature enables efficient regulation in standby and bias supply rails, while the 8-SMD gull-wing package supports automated assembly in space-constrained boards.
Industrial and Appliance Control Boards
The -40°C to 150°C (TJ) operating range and robust fault protection make the TNY274GN-TL suitable for control-board bias supplies in appliances and industrial equipment.
