Posting here instead of in the D3AA driver topic since it’s generally more Anduril related
3 channel LED driver :
- 2.4V-5.5V
- operating current : 80/120uA typ/max
- shutdown current : 1uA max
- regulated current options : 25, 15, 10, 5mA
- 8bit PWM dimming : 20uA steps at 5mA full scale
- I²C
- DFN 2x2mm
- dirt cheap
Depending how it can be programmed that looks like a good candidate for rich RGB
edit : 500Hz PWM frequency, could be better but for AUX LEDs it’s acceptable.
