The Power Integrations TNY290KG-TL is a flyback offline switcher from the TinySwitch-4 series delivering up to 28 W with a 725V breakdown rating and integrated switch. Packaged in a 12-BESOP with exposed pad, it offers galvanically isolated output, 67% max duty cycle, 124kHz to 140kHz switching, EN control, and comprehensive fault protection.
- Integrated switch simplifies isolated flyback designs and cuts component count.
- 725V breakdown voltage for robust offline operation.
- 28 W output suits compact isolated supplies.
- Fault protection (current limiting, open loop, over temperature, over voltage, short circuit) enhances reliability.
- Wide -40°C to 150°C junction temperature range.
