2 Introduction General Product Information 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 drivers the converter in the Quasi-resonant mode to achieve high 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. 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(ovp), over-temperature protection, and cycle-by-cycle current limitation. Product Feature Tight LED current regulation No opto-coupler and TL431 required Power factor correction(pfc) Compatible with analog dimming Built-in HV start-up device Quasi-resonant Maximum/Minimum switching frequency clamping Maximum/Mimimum on-time limitation Wide VDD range (up to 34V) THD optimization Input-voltage feed-forward compensation Multiple protection features LED open-circuit protection LED short-circuit protection Output diode short-circuit protection VDD UVLO VDD OVP Over-temperature protection Cycle-by-cycle current limitation EVB_RT November
