The Power Integrations TNY285KG-TL from the TinySwitch-4 series is an isolated Flyback offline switcher delivering up to 11 W. It integrates a 725V switch and switches at 124kHz to 140kHz with a 67% maximum duty cycle. Current limiting, open loop, over temperature, over voltage, and short-circuit protection ensure robust operation across a -40°C to 150°C junction range in a 12-BESOP package with exposed pad.
- Isolated Flyback topology provides galvanic isolation for safety-critical designs.
- Integrated 725V switch reduces external component count.
- 11 W output with 124kHz to 140kHz switching enables compact magnetics.
- Comprehensive protection: current limiting, open loop, OTP, OVP, and short circuit.
- Exposed-pad 12-BESOP package improves thermal performance.
Isolated Flyback Adapters
The TNY285KG-TL is a Flyback switcher delivering up to 11 W with galvanic isolation, ideal for compact chargers and adapters. Its 124kHz to 140kHz switching frequency enables small magnetics.
Standby and Bias Supplies
