LNK304DG Power Integrations SMD AC/DC Buck Converter IC, 85-265VAC, 170mA, 8-SOIC
The LNK304DG is an SMD AC/DC buck converter integrated circuit from Power Integrations. It replaces linear and capacitor-fed non-isolated power supplies. This monolithic IC integrates a 700V power MOSFET, an oscillator, and On/Off control. The device operates directly from the DRAIN pin, removing the requirement for a bias supply. It supports a universal input voltage range of 85-265VAC. The IC provides an output current of 170mA. Built-in auto-restart, current limit, and thermal shutdown mechanisms provide fault protection. Its compact 8-SOIC package is suitable for space-constrained applications.
