DIGITAL DIMMING CONTROL
Digital Control Signal Output current Digital Control Signal Output current(LED appears bright) Digital Control Signal Output current(LED appears dim)
This type digital dimming, which control output current adjusting pulse width signal. Io_set refres wanted output current value. Io_norm refers rated output current refers pulse width signal example: assume rated output current 300mA wanted output current 150mA, then pulse width should from equation above. That keep pulse width signal 0.5, output current will kept 150mA. natural driver generate audibly noise dimming process, because frequency control circuit within human audibly range (20Hz~20KHz).
