I am planning on powering a set of RGB LED strips (I am leading towards APA102 https://cdn-shop.adafruit.com/datasheets/APA102.pdf). I know that, at full brightness, each LED requires 60mA. So, at 30LEDs/m, that is 1.8A/m, or (5V x 1.8A =) 9W/m.
I will be using 13m, and so I need a (13*9W=) 117W power supply that can provide 23.4A at 5V.
My question is this. Can I use a 12V 10A (=120W) power supply, and 5 LM1084 voltage regulators in parallel to covert the 12V to 5V? Each LM1084 is rated for 5A output. http://www.ti.com/lit/an/snva558/snva558.pdf
Please excuse my ignorance. Perhaps my reasoning is off, or thee is a glaring safety hazard here. Please feel free to offer any helpful advice at all.
Thanks in advance.
