Hello,
I am working on a project with LED lights in lamp, I sourced the correct sized power adapter already for what I planned to use and then I realized any lamp without a USB charger in this generation is basically trash and makes me cry on the inside. Background set here's the question.
My known information is here- LED load is soaking up ~30 watts @12V's 3A. I want to add a USB charging port into the circuit.
From what I understand this is going to consume around 15w and I need to change my voltage to 5v 1.5A. My outlet adapter 12v 3A ~50w range
QUESTION- Whats the best way for me to accomplish this supply change cheaply? From what I have read and assumed its called BUCK converter but the terms seems broad vague (magical) and too general until I see the actual working solution. Am I on the right track? Any specific hardware links to clear up the mystery and save me from purchasing the wrong items would be greatly appreciated.
