TLC59108: About register setting for parallel outputs

Part Number: TLC59108

Hello,

 

Regarding to parallel outputs on TLC59108, my customer is asking some question.

Due to output current 200mA/ch for LED, they will use parallel outputs.

 

(Question)

1) When parallel outputs, how do they need configure PWM Registers?

For example, in case of below, PWM0/1,2/3.4/5,6/7 Registers need to set  each same value?

(max 240mA/ch)


 

2) Each channel maximum current is 120mA/ch. My understanding is correct?


 

 

Regards,

  • Hi Tao,

    1. It is recommended to set both channels at the same value, to avoid inducing irregular PWM, if 8-bit PWM dimming is enough for you.

    2. Yes the output can be controlled individually and all can output 120mA.
