The TNY278GN-TL from Power Integrations is a TinySwitch-III Flyback offline switcher delivering 28W with galvanic isolation. It integrates a 700V power MOSFET and operates at 132kHz with up to 65% duty cycle. Built-in current limiting, open loop, over temperature, over voltage, and short circuit protection enhance reliability. The 8-SMD gull-wing package supports junction temperatures from -40°C to 150°C.
- Integrated 700V MOSFET reduces external component count and board space.
- Galvanically isolated Flyback topology ensures safety separation.
- 28W output at 132kHz with 65% max duty cycle enables compact high-density designs.
- Comprehensive protection suite (current limiting, open loop, over temperature, over voltage, short circuit) improves reliability.
- Wide -40°C to 150°C junction range supports harsh environments.
