LNK606DG-TL – Power Integrations LinkSwitch-II Energy-Efficient CV/CC Offline Switcher IC

Quick Answer The LNK606DG-TL is a highly integrated offline switching IC from Power Integrations' LinkSwitch-II family. It combines a 700V power MOSFET with On/Off control for accurate constant voltage (CV) and constant current (CC) output regulation without requiring an optocoupler or secondary feedback circuitry. Capable of delivering up to 5.5W (universal input open frame) / 6.1W (230 VAC open frame), it is ideal for compact, cost-effective chargers, adapters, and LED drivers in a SO-8C package.
