The Power Integrations TNY279GN-TL is an isolated Flyback offline switcher from the TinySwitch®-III series with an integrated power switch, rated at 32W. It features a 700V breakdown rating, 132kHz switching frequency, and 65% maximum duty cycle in an 8-SMD (7 leads) gull-wing package. Protection includes current limiting, open loop, over temperature, over voltage, and short circuit, across a -40°C to 150°C (TJ) range.
- Integrated power switch simplifies design and reduces external component count.
- 700V breakdown rating suits offline mains-connected designs.
- Isolated Flyback topology provides galvanic separation between mains and output.
- Comprehensive fault protection including short circuit improves reliability.
- Broad -40°C to 150°C (TJ) range supports demanding thermal environments.
