TNY274PN

Product Description

TNY274PN General Description

The TNY274PN is a highly integrated offline switcher IC designed specifically for non-isolated flyback power supplies. It features a low power, high-efficiency design that eliminates the need for external diodes and capacitors. The IC incorporates a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, thermal shutdown circuit, and frequency jittering.With a maximum output power of 12.5W and a wide input voltage range of 85-265VAC, the TNY274PN is ideal for use in a variety of applications, including LED lighting, smart home devices, and consumer electronics. It is well-suited for compact designs due to its small form factor and minimal external components required.Key features of the TNY274PN include overvoltage and undervoltage protection, adjustable output voltage regulation, and low standby power consumption. The IC also features advanced safety and reliability features, making it a popular choice for designers looking for a high-performance, cost-effective solution for their power supply needs
