Dimming Methods  
VBAT  
12V  
Two methods for PWM dimming control on the LEDs  
are described below. The first method is to PWM on  
the control pin, the other method is to turn on and off a  
second resistor connected to the RSET pin and  
connected in parallel with R1.

CTRL  
A PWM signal from a microprocessor can be used for  
dimming the LEDs when tied to the CTRL pin. The  
duty cycle which is the ratio between the On time and  
the total cycle time sets the dimming factor. The  
recommended PWM frequency on the CTRL pin is  
between 100Hz and 2kHz.

PWM on RSET Pin  
Another dimming method is to place in parallel to R1  
another resistor with a FET in series, as shown on  
Figure 6. R1 sets the minimum LED current corres-  
ponding to 0% duty cycle. The combined resistor of  
R1 and Rmax sets the maximum LED current  
corresponding to 100% duty cycle.
