RT7304 - Primary-Side-Regulation LED Driver Controller

The RT7304 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 RT7304 controls t.
