LNK564PN Off-line Switcher IC

The LNK564PN Off-Line Switcher IC is a highly integrated AC-DC power conversion device designed for low-power switched-mode power supplies (SMPS). Part of the LinkSwitch™ family, this IC combines a high-voltage power MOSFET, oscillator, control circuitry, and multiple protection features into a single compact DIP package.

The LNK564PN is ideal for energy-efficient power supplies used in home appliances, standby power systems, chargers, industrial controls, and IoT devices. Its simple design requires minimal external components, reducing overall cost and board space while improving reliability.

With built-in protection features such as thermal shutdown, current limiting, auto-restart during short circuit conditions, and line under-voltage detection, the LNK564PN ensures safe and stable operation even in demanding environments. It is optimized for high efficiency and low standby power consumption.
