Can I Use Parallel Buck Converters to Achieve Higher Amperage?

Click For Summary
Using multiple 1A buck converters in parallel to achieve a total of 5A is possible, but requires a common controller to evenly distribute the load and prevent overheating. Without such a controller, one converter may draw more current, leading to thermal runaway. While individual calibration of each converter could help, it is not a reliable solution to avoid thermal issues. A more effective approach is to use current limiters on the outputs of each converter, allowing for a combined output without exceeding individual ratings. Ultimately, designing or purchasing a larger buck converter that can handle the required 5A is the most straightforward solution.

Say you need 10V on the output of the current limiter, the buck converter must yield 11V on the output.
11V - 1V = 10V.
ok, Thank you very much for your time. Thanks!
