How can I make a power supply that is able to give 4 amps in terms of current and 5 Volts fixed? I've made a power supply before with variable voltage however the amp output never went above 1A. Which materials must I implement and will it be able to run nonstop without the risk of overheating and fire?
Edit: this power supply will be used in a LED matrix with addressable chips, since this matrix is 10x10, then the total 100 LEDs will require at least 4 Amps.
Edit: This power supply will connect to the normal household electric connectors, therefore it's input will be 110v.
