9 Power Supply Recommendations

The supply voltage range is from 3 V to 5.5 V for the TLC6C5816-Q1 device, which typically uses the same supply voltage as the microcontroller, 3.3 V or 5 V. The LED supply voltage can be up to 40 V, so the LED supply can use a car battery directly. Ensure the LED current is no greater than 50 mA during load dump conditions. As the car battery varies a lot, to achieve stable LED brightness, a regulated voltage, for example 5 V, is preferred for the LED supply.
