RT7306 Description

The RT7306 is a constant current LED driver with active power factor correction. It supports high power factor across a wide range of line voltages, and it drives the converter in the Quasi-Resonant (QR) mode to achieve higher efficiency. By using Primary Side Regulation (PSR), the RT7306 controls the output current accurately without a shunt regulator and an opto-coupler at the secondary side, reducing the external...
