UGH FINE! I'll do the maths homework!

or... fuck that? I don't need anything special here I don't think. Power goes in, power comes out.
"The EN pin has an internal pullup current source, which allows the user to float the EN pin to enable the device”
Huh, I don't think I've ever seen this recommendation called out in a switching power supply IC datasheet before?
"Ideally, the saturation current rating of the inductor is at least as large as the high-side switch current limit,
IHS_LIMIT (see Section 8.5). This ensures that the inductor does not saturate even during a short circuit on the output. When the inductor core material saturates, the inductance falls to a very low value, causing the inductor current to rise very rapidly. Although the valley current limit, ILS_LIMIT, is designed to reduce the risk of current runaway, a saturated inductor can cause the current to rise to high values very rapidly, this can lead to component damage, so do not allow the inductor to saturate”
@jpm Normally this is assumed to be common knowledge.
@jpm perfect example of theoretical vs practical vs time-optimised
Theoretical: that fucken equation
Practical: 1.2V threshold, simple voltage divider calc using ~10k resistors so pin current is irrelevant
Time-optimised: slap down 2 x DNP resistors, float the pin and leave the option to do better later. Welp, it’s beer o’clock!
@jpm An electron leaves the capacitor towards the inductor travelling at 0.98c. Simultaneously the same electron leaves the inductor travelling towards the capacitor at 0.76c just to fuck with you. How over this shit are you in gigafarads?
@abstractcode L-C tank circuit go boioioioioioioioinnnnngggggggggggggg
