TLC5955: Flickering LEDs

$

Part Number:TLC5955

Hi team,

On operating the TLC5955 there is some unexpected behavior.

To begin with, some outputs generated different brightness for the LEDs, despite the LEDs and all settings (GS, DC, BC) being equal.

Additionally, there was a flicker on the outputs when more than three channels were active simultaneously, even though the GS-settings were ensured to have the same value. Flickering always occurred independent of GS-value

What would be your first advice when troubleshooting?

Kind regards,

Gustaf
