LP8867Q1EVM: Different LED per channel cause Fault

Part Number: LP8867Q1EVM

Hello team,

I have connected 8 LEDs on OUT1 -> no problem
I have connected 9 LEDs on OUT2 -> no problem

I have connected 8LEDs on OUT1 and 9LEDs on OUT2 @ PWM Duty 100% -> device output FLT signal.
The VBoost was 33V.

The voltage at OUT1 and OUT2 were all withing the 0.9V - 5.5V range, so they were within the VLOW_COMP to VHIGH_COMP range.

Do you have any idea why does EVM not work for different LED numbers on 2 ports?

Best Regards,
Kei Kuwahara
