TNY268PN IC
Br 100.00
- The TNY268PN is an energy-efficient, low-power, offline switcher IC from Power Integrations, typically used in AC-DC flyback converters up to 15W. The TinySwitch™-II family integrates a 700 V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single monolithic device. It eliminates the need for bias windings, reducing cost and design complexity.
