Boost – DC to DC Boost Converter Low Frequency

TLRD: your calculations are fine. I got myself confused by checking them against a different calculator that targeted DCM not CCM. I'm not gonna change the stuff below because Arsenal replied to it, and it might also be useful to you to compare the two modes.

Your inductor looks an order of magnitude too big vs what I get at https://learn.adafruit.com/diy-boost-calc/the-calculator

And it does look like your inductor is far too big:

@Arsenal N.B.: I figured out the difference between these two calculators. The adafruit one gives you a DCM (discountinous current mode) solution, whereas TI's gives a CCM solution.

Which one is preferable depends on various factors. Basically at high output currents you want CCM to lower the losses and stresses on the components, but DCM has better transient response. A lot more about that can be read here, including a side-by-side power efficiency calculation example.

You hearing voice in your head or from other places they shouldn't be is a medical issue, not a electrical engineering one.

However, this buck controller is inappropriate for applications where the load might get very light or go to zero. Note that the on time for the switch is at least 210 ns. It also seems that this device uses a fixed frequency. I didn't read every word of the datasheet (that's your job), but didn't see mention of pulse skipping, and it's pretty clear the frequency doesn't get changed.

If you need to support very low load currents, then use a controller that can switch between PWM and PFM, or do cycle skipping. It appears this one doesn't.

You could add a resistor to always guarantee the minimum required load current, but that's really a hack working around having the wrong controller in the first place.
