The Power Integrations TNY174DG-TL is an isolated Flyback offline switcher with secondary-side SR and an integrated switch, rated at 650V breakdown. It delivers up to 11W at 132kHz switching frequency with a 65% maximum duty cycle. Protections include current limiting, over load, over temperature, over voltage, and short circuit, with EN control. Housed in an 8-SOIC (7-lead) package rated for -40°C to 150°C junction temperature.
- Isolated Flyback topology with secondary-side SR provides galvanic isolation for safety-critical designs.
- Integrated 650V switch simplifies the power stage and reduces external parts.
- Up to 11W output supports compact adapters and bias supplies.
- Broad protection suite (current limiting, over load, over temperature, over voltage, short circuit) enhances reliability.
- High 150°C junction temperature rating suits thermally demanding environments.
