LNK306 - Energy-Efficient Off-Line Switcher

Download the LNK306 datasheet PDF. This datasheet also covers the LNK302P variant, as both devices belong to the same energy-efficient off-line switcher family and are provided as variant models within a single manufacturer datasheet.

Description

LinkSwitch-TN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency.
