Digital Control with PWM
A is PWM and B is Low.
I
LED
(Average) =
δ
x 7mA where
δ
is Duty Cycle. (Note 3)
A is High and B is PWM.
I
LED
(Average) = 7mA +
δ
x 14mA where
δ
is Duty Cycle. (Note 4, 5)
Notes:
3. Proportionally select the duty cycle to achieve a typical LED current between 1mA to 6mA.
4. If either input A or B is high continuously, the other input can be modulated at a maximum rate of 30kHz. If this is not the
case, the maximum rate of modulation should be limited to 1kHz.
5. Proportionally select the duty cycle to achieve a typical LED current between 8mA to 20mA.

Digital LED Brightness Control
1. Digital Control
A digital to analog converter selects the following modes of
operation: OFF, 7mA, 14mA, 21mA per diode. In addition,
by turning the "IN B" pin ON and OFF , the current can be
modulated between 8 to 20mA to achieve any I
average
value.
2. Digital Control with PWM
Any pin can be modulated by a variable duty cycle (
train. Care should be taken not to use too low frequency,
otherwise a flickering effect can be seen.The minimum range
is between 100Hz to 5KHz. For a maximum range of LED
current, both A and B can be modulated at the same time.
