Other Parts Discussed in Thread: TLC6C5712-Q1

Tool/software:

I am designing an LED control schematic featuring a common-anode RGB LED. Is it possible to control the RGB LED using the circuit shown in the provided below link (3rd page, Figure H)? Please review the details and suggest modifications if necessary.

    Hi Ravi,

    This device supports a constant current source topology which is shown below. For a common-anode RGB LED, if you want to achieve an individual R, G, B control, you will need a current sink topology, like TLC6C5712-Q1. What's your application? please share more details, like LED number, current... for a better recommendation. Many thanks!
