LNK3206D-TL – Power Integrations LinkSwitch-TN2 Energy-Efficient Offline Switcher IC

Quick Answer The LNK3206D-TL is a highly integrated offline switcher IC from Power Integrations' LinkSwitch-TN2 family. It combines a 725V power MOSFET with On/Off control in a compact SO-8C package. Designed for non-isolated buck, buck-boost, and flyback topologies, it delivers up to 225 mA (MDCM) / 360 mA (CCM) output current with excellent efficiency and comprehensive system-level protection. It is an advanced, high-reliability upgrade over the classic LinkSwitch-TN series for low-power offline applications.
