LNK501PN General Description

The LNK501PN is a LinkSwitch-4™ integrated off-line switcher IC that provides high efficiency, robustness, and proven reliability for low power applications. It features an integrated 700 V power MOSFET, a constant current (CC) primary-side control scheme, and a multi-mode flyback controller to achieve high efficiency and precise constant current output regulation. The device is designed to deliver up to 10 W of output power in non-isolated buck, buck-boost, or flyback topologies.The LNK501PN includes various safety features such as auto-restart protection, output overload protection, and thermal shutdown to ensure reliable operation in harsh operating conditions. It also offers a wide range of input voltage capability from 85 VAC to 265 VAC, making it suitable for a variety of low power applications including LED lighting, home appliances, and industrial controls.The device comes in a compact, thermally enhanced 8-pin package and is highly cost-effective due to its low component count and high level of integration.
