The RT7306D 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 RT7306D 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 RT7306D 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 RT7306D to minimize the power loss and shorten the start-up time.
The RT7306D 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.
