SoBotz A2B Buck Regulator Prototype

This buck regulator is insanely small with powerful specs!
The STI3470 chip allows up to 2A of current (although we found a 3A chip, but we still need to do some testing).
Using high quality Wuerth Elektronik inductors

Input voltage: absolute maximum up to 23v (but recommended 18v)
Dimensions: 10x16x5mm
Voltage ripple:

During our testing we did achieve 1.9A, but we don’t suggest using this buck at such loads, because it gets very hot. We suggest using at shorter peak loads as it’s more fit for that.
The final design will have jumpers for 3.3, 5 and 7.4V outputs, but do note, that this is a buck regulator, so to get the lower voltage, the input voltage should be at least 1.5v higher than the output.
