PWM Control (AAT3192/93-4 only)
PWM (Pulse Width Modulation) is an industry stan-
dard technique of controlling LED brightness by
modulating the conduction duty cycle of the LED
current. LED brightness is determined by the aver-
age value of the PWM signal multiplied by the LED’s
intensity where intensity is proportional to the LED
drive current. A PWM control signal can be applied
into the EN/PWM pin of the AAT3192/93-4. By
changing the duty cycle of the PWM signal from
100% (logic high) to 10%, LEDs sink current can be
programmed from 20mA to 2.4mA. To save power
when not used, AAT3192/93-4 can be shutdown by
holding the EN/PWM pin low for 1ms.
Lastly, Table 4 and Figure 5 illustrate the
AAT3192/93-4’s LED current control profile as a
function of a PWM control signal.
