Application Information
(Continued)
which will result in reduced LED intensity. A PWM frequency
setting of 60Hz results in an optimal balance between LED
accuracy and intensity.
DRIVING RGB LED MODULES
The LM4970’s PWM LED outputs can be used to drive
individual color LEDs or RGB LED modules. When driving
RGB LED modules in audio synchronization mode, the color
and intensity of the RGB LED module will be dependent on
the audio input signal. In I
2
C pattern mode, the RGB LED
module can be set to any of seven distinct colors, based on
the status of the I2C_LED1, I2C_LED2, and I2C_LED3 bit
settings.
