Part Number: TPS61196
We plan to use part TPS61196 to drive below LEDs:
Is this possible with this part ?
If not, can you help suggest a suitable solution ?
Appreciate your response.
Since there is a big voltage difference between this two LED strings, I would not recommend just use this way since this will lead to a high thermal issue, I would recommend adding some resistors to match the voltage difference for the Red LED string. That would have better thermal performance.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Sean Zhou:
Thank you for your advice, I appreciate it.
Can you help advice appropriate values for the resistors to match this RED LED string voltage difference ?
In reply to Ryan Delfino:
Please use the below equation to calculate the resistor:
R=(Difference voltage between two channels) / (Current for each channel)
Can you help check if below diagram is correct based from my understanding to your advice?
Yes, you have got the right circuit, please go on and any further question, please let me know.
