TNY268PN,Enhanced Off-Line Switcher,DIP-8B

The TNY268PN-DIP is a high-efficiency, energy-saving off-line switcher designed for low-power applications. It combines a 700V power MOSFET, an oscillator, and control logic into one monolithic device, simplifying power supply designs. The device is optimized for delivering up to 16W of output power in adapter designs and up to 23W in open-frame designs, while operating over a wide input voltage range of 85-265VAC.

This switcher features built-in protection mechanisms, including thermal shutdown and current limiting, ensuring reliability and safety during operation. Its high switching frequency of 132 kHz allows for the use of smaller, cost-effective external components. Additionally, the TNY268PN-DIP incorporates frequency jittering to reduce EMI emissions, making it an ideal choice for energy-efficient designs that meet global regulatory standards such as Energy Star and CEC.

Packaged in a compact DIP-8B form, the TNY268PN-DIP is perfect for applications with space constraints. This device eliminates the need for a bias winding and offers simple ON/OFF control with integrated auto-restart, providing a reliable, low-component solution for adapters, chargers, and standby power supplies.
