EVB_RT7306+RFID: 36V @ 250mA, 90 ~ 264 VAC, Dimming, w/ RF Supply

Summary

The EVB_RT7306+RFID Evaluation Board highlights the functionally of the RT7306 constant current LED driver IC from Richtek along with the compatibility of incorporating an RF module for remote control of LED fixtures, making it a perfect addition to the Internet of Things (IoT) ecosystem or smart home automation lighting solution.

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 component count, the cost, and the volume of the driver board.
