LNK6669E

AC DC Converters, Offline Switchers Overview

The LNK6669E is an AC/DC converter from the LinkSwitch-HP family, designed for high-power offline flyback applications. It integrates a primary-side regulated (PSR) controller and a 650V power MOSFET in a single package. The device supports output power up to 77W at 230VAC and 56W across the universal 85-265VAC input range. Operating with a switching frequency of 132kHz, it utilizes multi-mode control to maintain efficiency across varying loads while minimizing audible noise.
