Did uSOM820 support WLED? Is "PMI8994_VREG_WLED" the voltage output of PMI8994 WLED booster?My display backlight is 7S3P/1.6W, max. current is 24mA, max. voltage is 23V. Can uSOM820 support this configuration?
As my experience, both sSOM820 and oq820 have wled booster, which contains 4(3 on uSOM820) sinks to be adjustable, though, I add a PWM power IC for CABC feature.
I also found WLED related component in SOM schematic. I just want to make sure WLED was functional verified during the development.
Yes, PMI8994_VREG_WLED is the output of the PMI8994 WLED booster. The max output voltage of the booster is 28.5V and max current is 30mA. It will support your display backlight. As mentioned by @henry.chuang, please note that there are 3 WLED sinks on the uSOM 820. Lastly, yes we have tested the WLED with Intrinsyc's standard display used on the uSOM 820 development kit.
It's really good news.I don't need extra backlight driver!Thanks jmok
