Other Parts Discussed in Thread: TPS92515
Hi, TI expert
Constant Current LED Driver Inquiry about RGB LED color problems due to output deviation when outputting low current.
Using three TPS92515-Q1, RGB LED is currently being used in 3S68P structure.
At the lowest brightness, the current of about one channel is controlled around 30mA, but the green brightness value is large compared to Red/Blue, so the color difference is felt even with small deviations.
The color changed after replacing only the corresponding channel driver chip of the product where the green was strong.
It would be nice if there is no current control deviation, but if not, please consider whether there is a way to reduce the deviation with the peripheral circuit configuration.
Please provide detailed answers to the above issues.
