The Power Integrations TNY175PN is an isolated flyback AC-DC converter IC with an integrated power switch and a 650V breakdown rating. It delivers up to 15 W and operates at 132kHz with a 65% maximum duty cycle, using secondary-side synchronous rectification for isolated output. Built-in current limiting, over load, over voltage, over temperature, and short circuit protection support robust designs across a -40°C to 150°C junction temperature range in an 8-DIP package.
- Integrated power switch reduces external component count and simplifies isolated flyback design.
- 650V breakdown voltage supports universal AC input margins.
- Secondary-side synchronous rectification improves isolated output performance.
- Comprehensive fault protection (current limiting, over load, over voltage, over temperature, short circuit) enhances reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
Compact AC-DC Adapters
The TNY175PN's integrated switch and 650V breakdown rating make it well suited for compact isolated flyback adapters operating from universal AC input. Its 132kHz switching frequency helps keep the transformer small while the 15 W power capability covers chargers and small power supplies.
Standby and Auxiliary Supplies
With secondary-side synchronous rectification and a 65% maximum duty cycle, this device supports efficient isolated auxiliary rails in appliances and industrial equipment where reliable regulation and integrated protection matter.
Home Appliance Power Boards
The wide -40°C to 150°C junction temperature range and comprehensive fault protection (over load, over voltage, over temperature, short circuit) allow the TNY175PN to serve in appliance control boards requiring isolated low-power rails.
Metering and Control Electronics
Designers of metering and control modules can use the flyback topology with integrated MOSFET to build isolated supplies up to 15 W, reducing BOM count while retaining current limiting and short circuit safeguards.
