(1). Dimming using PWM signal into CTRL0 and CTRL1  
LED current can be controlled by applying a PWM signal to CTRL0 or CTRL1. Table 4  
shows the relation between CTRLx and 4 LED's current states. For an example, as the  
CTRL1 is pulled logical high and CTRL0 receives a PWM signal, then, four LEDs will be  
dimmed synchronously. Here, the PWM signal setting the LED's current ON/OFF can  
achieve the average LED's current which in design. The application circuit is shown in  
Figure 4. Figure 5, and Figure 6 show 3WEDs and 2WLEDs PWM dimming application  
circuit, respectively. During the time of PWM signal logical low, the current is a fixed value  
and setting by RSET resistor. So the average LEDs current can be approximated as  
Equation (3).
