Primary-Side Regulation Dimmable LED Driver Controller with Active-PFC
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.,,The RT7306 is compatible with analog dimming. The output current can be ,modulated by the DIM pin. An in-house design high voltage (HV) start-up device ,is integrated in the RT7306 to minimize the power loss and shorten the start-up ,time.,,The RT7306 embeds comprehensive protection functions for robust designs, ,including LED open-circuit protection, LED short-circuit protection, output ,diode short-circuit protection, VDD Under-Voltage Lockout (UVLO), VDD ,Over-Voltage Protection (VDD OVP), Over-Temperature Protection (OTP), and ,cycle-by-cycle current limitation.,,
