MAX8596Z drive circuit diagram of eight white LED

  
Driving series white LED, flowing through the same song in each white LED current, it is possible to obtain a uniform brightness. The disadvantage of the tandem drive is the dr

ive voltage for the white LED forward voltage drop and the sum of the drive output voltage amplitude should meet after the series LED drive voltage required. This configuration requires tandem switch inductive boost converter in order to obtain high efficiency at high pressure. When choosing this type of converter must be considered LX pin rated output voltage. The table below shows several inductive boost switching converter Lx pin rated voltage and can drive series white LED number. The need to retain the maximum voltage between the maximum rated voltage of white LED in series with the Lx pin certain safety margin to allow for overvoltage shutdown. Select the appropriate table series LED device drivers required
