Note: The negative output terminal can ’t connect GND, or the module may be damaged. DIGITAL DIMMING CONTROL PWM Digital Control Signal 0 1 0 1 0 1 0 1 0 1 PWM Digital Control Signal PWM Digital Control Signal Output Current Output Current(LED appears bright) Output Current(LED appears dim) For the rated frequency PWM dimming, the output current of driver matters to the pulse width of the PWM signal, and the numerate please refer to the following formula: T Io_norm Io_set = (DT-0 .6) Io_set refers to the expected output current value. Io_norm refers to the rated output current D refers to the pulse width of the PWM signal T refers to the cycle of the PWM signal Note: The formula only supplies as a reference, and the output current may be a little deviation with different load. The Ton(min) of PWM signal must be greater than 0.7ms, or the driver can ’t be operated normally. It is natural for the driver to generate an audibly noise in dimming process, because the frequency of the control circuit is within human audibly range (20Hz~20KHz). In order to avoid the human eye can observe the LED flashes, the PWM dimming frequency is recommended to set above 100Hz. |
