The TNY285DG-TL from Power Integrations is a flyback offline switcher in the TinySwitch®-4 series, delivering up to 8.5 W with a 725V breakdown rating. It integrates the internal switch for a compact isolated design, runs at 124kHz to 140kHz with 67% maximum duty cycle, and includes current limiting, open loop, over temperature, over voltage, and short circuit protection. Supplied in a 7-lead 8-SOIC package rated for -40°C to 150°C junction temperatures.
- Integrated internal switch reduces external component count and simplifies isolated flyback designs.
- 725V breakdown voltage provides a wide Vds margin for offline operation.
- Comprehensive fault protection (current limiting, open loop, over temperature, over voltage, short circuit) improves reliability.
- EN control feature enables flexible on/off regulation.
- Wide -40°C to 150°C junction temperature range suits demanding thermal environments.
Compact AC-DC Adapters
The 8.5 W power capability and 725V breakdown rating make this flyback switcher well suited to small isolated adapters and chargers where a robust Vds margin is needed.
Standby and Auxiliary Supplies
With an integrated switch and EN control feature, the TNY285DG-TL simplifies isolated bias supply designs, reducing external component count in auxiliary power rails.
Home Appliance Control Boards
