LNK3204D-TL

LNK3204D-TL is a highly energy efficient off-line switcher IC with integrated system level protection for low component-count power supplies. LinkSwitch™-TN2 family of ICs for non-isolated off-line power supplies provides dramatically improved performance compared to traditional linear or cap-dropper solutions. Designs using the highly integrated LinkSwitch-TN2 ICs are more flexible and feature increased efficiency, comprehensive system level protection and higher reliability. The device family supports buck, buck-boost and flyback converter topologies. LinkSwitch-TN2 ICs consume very little current in standby resulting in power supply designs that meet all no-load and standby specifications worldwide. MOSFET current limit modes can be selected through the BYPASS pin capacitor value. Typical applications include metering, Smart LED drivers and industrial controls and IOT, home and building automation.
