Hi Experts,

Would like to ask using the GUI of LP8866EVM:

After this configuration on LP8866EVM GUI software, only the first 8 columns of LEDs are glowing. Remaining are not glowing. How to enable all the LED?

Thank you.

Hi, Archie

You can take off the shading board and change the jumper.

Hi Zhiqian,

As you said, we take off the shading board and changed the jumper. But till 14th Column only able to move to enable LED. If we move the jumper to the 15th column, we're getting Global Faults.

Diver can't enable all the LEDs at a time?? Or is there any solution for this? Kindly provide your feedback.

Thank you.

Hi, ArTzy

For 15LED, the total output voltage is higher than 45V, and it may see some fault.

What is the target LED number you want? Maybe I could give you some solution.
