Does anyone have a design for a 1-3A step-down DC/DC converter including EMI filter etc. using components available from LCSC that I could reuse or base my own design on? Even using a ready-made module (78xx replacement style) I'm going crazy with inductor selection for the input and output filters. As long as it's working well (especially EMC wise) and not too large I don't care much if it uses a ready-made module or individual parts.

Anyone out there used a buck converter to power a #pi5 from a power bank?

Getting that ideal 5V 5A combination seems impossible from unmodified power from portable sources. A DC-DC step down should be able to generate that V and A. But the voltage input has to be within a specified range to get the desired A.

Sure, the 5 can run off of lower amperage but not at all well. I'm looking to get the same performance as though I were using the official 27W power supply.

Also, WTH is up with the math? 5.1V and 5A does not equal 27W! I guess that 27W rating is the upper bound as the supply can also take in 9V 3A (27W). The supply must itself be using a buck converter. I just need one a LOT smaller. I'm aware of boards like this that may do the trick. a.co/d/dU6wNU3

So, on my last DC-DC converter, I left off messing around with the control loop. I got it working decently, but there were still some oscillations. Thinking about it, this was probably due to ADC resolution, which is 10 bits on that microcontroller, while the PWM register I was using is 8 bits.

If you think about it (which I didn't initially), that means that you get quantization error, since the ADC can read voltages and currents the PWM (via the MOSFETs and the rest of the converter) won't produce. In other words, the controller is demanding more than what the converter can do.

I think I can maybe add some extra filtering to fix that. In the future, I'll try using the 16 bit register for PWM as well.
