Hi there,
I would like to increase the output current of the LED string.
Is it possible to do this with below connection ? Do you have any issues with it ?

Hi Ryan,
No, thst for pulse current with 400mA, we only recommend for maximum 200mA for each channel so for 500mA, we recommend minimum 3 channels.

Hi Sean,
I plan to drive 5 LED strings with each string containing 28 LEDs.
The current for each string are as below:
Given this requirements, please help confirm that using part TPS61196 is not suitable in our design.
If yes, can you help advice another part that meets this requirement ?

Ryan
Hi Ryan,
I'm sorry that TPS61196 can't set the different full-scall current for each channel, and it is better not to set over 200mA for each channel, I would suggest with the solution with several TPS61196.
