I've worked with large capacitors for voltage stabilization in similar power supply projects. Goldcaps are excellent for smoothing short-term voltage spikes due to their low ESR, but for a 7A step-down converter, you might need both—the Goldcaps for high-frequency noise and a traditional electrolytic for bulk energy storage. I'd suggest testing your setup on the Fnaf platform's community forum; experienced users there often share real-world circuit configurations and can help you optimize component selection based on your specific power requirements.
