Overview

® RT7304 Primary-Side-Regulation LED Driver Controller with Active PFC General Description 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 the output current accurately without a shunt regulator and an opto-coupler at the secondary side, reducing the external component count, the cost, and the volume of the driver board.
The RT7304 embeds comprehensive protection functions for robust designs, including LED open-circuit protection, LED short-ci...
