Hi,
What is the minimum current load on the OUTn pins? I'm looking to run 4 chains of LEDs at low current (a few mA per chain) - is such a low load likely to cause any issues?
Also, is there a minimum load for the boost converter?
Many thanks

Hi, Pjs,
Proper engineer has been assigned to take a look at this and will reply you soon.
Hi,
The maximum current set with Riset resistor or with DRV_LED_CURRENT_SCALE EEPROM bits can't be too low. The current accuracy is not quite good at a very low current setting. But you can set the maximum current at a high level, such as 150mA, and then use the register LED_CURRENT_CTRL[11:0] or DISP_CL1_CURRENT[11:0] to set the current. In that case, you can get very small current. And there's no issue to set a low current.
There's no minimum load for the boost converter.
