EVB_RT7306GS: 46V @ 920mA, 90 ~ 300 VAC
The EVB_RT7306GS is a constant current LED driver evaluation board 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.
