The TNY174PN from Power Integrations is an isolated flyback offline switcher with an integrated 650V power MOSFET and secondary-side synchronous rectification. Delivering up to 11 W at 230 VAC, it operates at 132 kHz with 65% maximum duty cycle and includes current limiting, over load, over temperature, over voltage, and short circuit protection. Housed in an 8-DIP package, it suits compact offline power designs.
- Integrated 650V MOSFET reduces external component count and board space.
- Secondary-side SR flyback topology improves isolated conversion efficiency.
- Comprehensive fault protection (OCP, OLP, OTP, OVP, SCP) enhances reliability.
- Wide -40°C to 150°C junction temperature range supports demanding environments.
- EN control enables flexible on/off regulation.
