I have one DC input 24V, 5A. I have designed a 4 channel led driver using the PAM2804 for Cree RGBW leds. I am using 3 of them. So, 3 Rgbw leds, and 3 led drivers. I need to be able to control individual r,g,b,w channels, and select if I want to use 1,2 o 3 leds. An arduino supplies the control signal to the PAMs.
My question, is how to convert the 24V, 5A into four 5V, 3A(max) sources. I hav been using LM2596, or XL6009E1, to convert 24V into one 5V, 3A source. But connecting several LM2596s in series to a 24v power supply seems not to work, one of them gets almost all the voltage. I have used them both in adjustable and fixed output. What can I use instead?
EDIT the picture shows 12V 5A; that is not correct, it is 24V 5A; as described in the text description. Thanks for pointing it out.
