Hi,
Looking for led-driving solutions that can match the following:
- ultra compact footprint
- < 5mA per LED (RGB as well as White)
- pwm dimming
- can't judge if constant current "is" a requirement to avoid buying expensive binned led's to get even brighness and chroma.
- I'm ok with factory calibration using CCD or photo-diodes for each led-channel.
- high refresh-rate
- the cross-plexing solutions out there I've tested is too slow, shaking the head or filming with a phone shouldn't reveal flicker & scan-rate.
- 1.8V logic/vddio (SPI/I2C control)
- I've looked around and for some reason all IC's (I've checked) on the market requires 3.3V
Looking forward to guidance!
