In this setup, we've employed the TPS61197 IC to boost the voltage for both the inner and outer LED rings. The inner ring LEDs require separate brightness control from the outer ring LEDs. The inner ring comprises 18 LEDs, while the outer ring has 34 LEDs.
For the inner ring, the total series LED voltage is approximately 3V x 18 = 54V. Each LED can draw up to 200 mA of current, resulting in a total LED string current of 200 mA. To achieve this, we need a step-up LED driver capable of delivering 54V/200 mA from a 12-24 volts power source.
For the outer ring, the total series LED voltage is approximately 3V x 34 = 102V. Similarly, each LED can draw up to 200 mA of current, leading to a total LED string current of 200 mA. To power this, we also require a step-up LED driver capable of supplying 102V/200 mA from a 12-24 volts power source.
The inner LED driver circuit is functioning perfectly, as demonstrated in the video. However, the outer LEDs' driver circuit encounters an issue—it boosts the voltage but briefly turns on the LEDs and then turns them off immediately.
There appears to be an issue with the outer LEDs' driver circuit.
