I have WS2812B LED strips, that has 144 LEDs per meter. The ratings are:
- 43W/M .3W/LED
- .06A per LED
- Input Voltage of 5V DC
The recommended power supply stated by the website is 5V DC and 10A for 1 meter. If I wanted to use 400 LEDs that would be 2 7/9 meters. If I based my power supply on the recommendation, that would be around 5V DC and 30A, right?
The question is:
- Is it possible to use a 12V battery, use a buck-down converter to 5V DC and 40A, and power the LED strip through the buck without doing any damage to the strips?
Thanks!
