Power Integrations TNY256PN
The TNY256 extends the power range of the TinySwitch family of energy efficient, low power off-line switchers. They integrate a 700 V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry into a single, monolithic device. The devices start-up and operate on power derived from the DRAIN voltage, eliminating the need for a transformer bias winding and associated circuitry.| Part No. | TNY256PN |
