The RT7310 is a high power factor constant current LED driver which is optimized for the compatibility with phase-cut dimmers. 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), RT7310 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 RT7310 supports phase-cut dimmers, including leading-edge (TRIAC) and trailing-edge dimmers.

RT7310 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 (OVP), Over-Temperature Protection (OTP), and cycle-by-cycle current limitation.
