Digital Control with PWM
A is PWM and B is Low.
I
LED
(Average) =
δ
x 7mA, where
δ
is Duty Cycle. (Note 2)
A is High and B is PWM.
I
LED
(Average) = 6mA +
δ
x 12mA, where
δ
is Duty Cycle. (Note 3, 4)
Notes:
2. Proportionally select the duty cycle to achieve a typical LED current between 1mA to 6mA.
3. If either input A or B is continuously high, the other input can be modulated at a maximum rate of 30kHz. Otherwise the
maximum rate of modulation should be limited to 1kHz.
4. Proportionally select the duty cycle to achieve a typical LED current between 8mA to 19mA.
