LNK632DG-TL – Power Integrations LinkSwitch-II Energy-Efficient CV/CC Offline Switcher IC

Quick Answer The LNK632DG-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 3.1W in both open frame and enclosed designs, it is ideal for ultra-compact, cost-effective low-power chargers, adapters, and LED drivers in a SO-8C package.
