PWM Control
1. A is PWM Controlled, B is Low.
I
LED
(Average) =
δ
x 5mA, where
δ
is Duty Cycle. (Note 3
)
2. A is High and B is PWM.
I
LED
(Average) =
5mA +
δ
x 15mA, where
δ
is Duty Cycle. (Note 4)
3. A and B are PWM.
I
LED
(Average) =
δ
x 20mA, where
δ
is Duty Cycle. (Note 5
)
Notes:
3. Proportionally select the duty cycle to achieve a typical LED current between 1mA to 4mA.
4. Maximum PWM frequency can be 30KHz.
5. Proportionally select the duty cycle to achieve a typical LED current between 1mA and 19mA.
