The TNY178DG-TL from Power Integrations is an isolated flyback AC-DC converter with an integrated power switch and secondary-side synchronous rectification. It offers a 650V breakdown voltage, 26 W output power, 132kHz switching frequency, and 65% maximum duty cycle. Comprehensive protections include current limiting, over load, over temperature, over voltage, and short circuit. Housed in an 8-SOIC 7-lead package, it operates across a -40°C to 150°C junction temperature range.
- Integrated power switch reduces external component count and simplifies flyback design.
- 650V breakdown voltage supports universal AC input applications.
- Secondary-side synchronous rectification improves isolated output efficiency.
- Comprehensive fault protection (current limiting, OLP, OTP, OVP, SCP) enhances reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
