The TNY288DG-TL from Power Integrations is a TinySwitch®-4 flyback offline switcher delivering up to 14.5 W with a 725V breakdown rating. It integrates the internal switch for a compact isolated design, runs at 124kHz to 140kHz with 67% maximum duty cycle, and includes current limiting, open loop, over temperature, over voltage, and short circuit protection. Supplied in a 7-lead 8-SOIC package rated for -40°C to 150°C junction temperatures.
- Higher 14.5 W output in a compact isolated flyback design.
- Integrated internal switch reduces external component count.
- 725V breakdown voltage provides wide Vds margin for offline operation.
- Comprehensive fault protection (current limiting, open loop, over temperature, over voltage, short circuit) improves reliability.
- EN control feature enables flexible regulation; wide -40°C to 150°C junction range.
