I have a WS2812b (NeoPixel) strip controlled by ATmega and powered by 5 V 2 A cell-phone style charger (from Digi-Key). The strip itself is located about 1.3 m away from the power source and microcontroller. The whole circuit would not consume more than 1 A (theoretical limit 4-6 A at full brightness).
Design guidelines on Adafruit and other sources suggest adding a 1000 µF capacitor at the beginning of the strip to help with power surges and stability, which I have in my existing circuit and there are no issues running this set up whatsoever. However I would like to add some safety components to the circuit, primarily in a form of a fuse straight out of the power supply. I am thinking adding 1.5 A fuse, but I am concerned that sudden inrush current on a large capacitor can blow the fuse upon initial connection to power. Would a 1.5 A slow blow (or even fast blow) fuse be OK for this application or do I need to design a dedicated slow-start circuit?
Schematics is below:
Update: I added the theoretical maximum of the circuit (4-6 A as there are close to 100 pixels current limited by software - thus the need for a fuse)
