The Power Integrations TNY177PN is an offline switcher IC built around a Flyback topology with secondary-side synchronous rectification, delivering up to 23.5 W in a galvanically isolated configuration. It integrates the power switch with a 650V breakdown rating and operates at 132kHz with a 65% maximum duty cycle. Comprehensive protections include current limiting, over load, over temperature, over voltage, and short circuit, housed in an 8-DIP package rated for -40°C to 150°C junction temperatures.
- Galvanically isolated Flyback design with secondary-side SR for safe, efficient offline power conversion.
- Integrated switch and 650V breakdown rating reduce external component count and simplify design.
- 132kHz switching frequency supports compact magnetics.
- Comprehensive fault protection (current limiting, over load, over temperature, over voltage, short circuit) improves reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
Isolated AC-DC Power Supplies
The TNY177PN uses Flyback topology with secondary-side synchronous rectification to deliver galvanically isolated output up to 23.5 W, making it well suited for compact offline power supplies that require safety isolation.
Chargers and Adapters
With an integrated switch, 650V breakdown rating, and 132kHz switching frequency, this device simplifies adapter designs by reducing external component count while maintaining robust current limiting and short circuit protection.
