LNK624DG-TL – Power Integrations LinkSwitch-II Energy-Efficient CV/CC Offline Switcher

Quick Answer The LNK624DG-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 11W in open frame (8W enclosed), it is ideal for higher power chargers, adapters, and LED drivers in a compact SO-8C package.
