Manufacturer:TI Description:The brightness of the LEDs can be easily controlled by injecting a PWM (Pulse Width Modulation) signal into the enable pin of the regulator, using a logic control, or applying a DC voltage from the DAC. Figure 4 shows a 400Hz PWM signal can be used to control the LEDs current by varying the duty cycle of the PWM signal. Figure 5 shows a logic signal and a transistor can be used to switch the LEDs current from 8mA to 1mA and vice versa. Figure 6 shows a DAC can be used to modulate the LED's current. |
