Meshnetn00b: a SMPS based power brick rectifies the AC at mains voltage, then uses a digital switching converter to pulse it through a transformer. You can use a linear regulator to get from 5V to 3.3V Meshnetn00b: for low voltage, low current supplies I would just buy a USB charger (not necessarily an apple one)

They're pretty complex, but why not use something off the shelf

Is that something I should expect to re-create myself very simply? I'm trying to come up with a way of safely powering a 3.3v ESP. LTSpice has no LED model for 50 mA or I'm missing something ? The extra diode is just to make sure the output starts off at 5V, for the demonstration Meshnetn00b: it's a switching power supplyДay: - this should illustrate it hopefully (except I just read your message saying you'd already done it.) I rectified and transformed down to about 12v, but ended up with only about 8.6v 'cause it was literally my first ever project product. So, I tried once to make a power supply for an old record player. So the psu is providing the current for the coilДay: have you tried running the circuit in falstad to understand its operation? My understanding is that the coil has a + and - pole while it is providing the energyД«ut im guessing you are telling me that the PSU and the coil are in series. Viper-7: needs one of those old analogue bakelite meters off Dr. Well i was unsure about the GND -> back to coil resistance Okay, so in this circuit, why does that create a voltage spike? Well it acts as a 'constant current' source. I was just thinking of the voltage spikes the inductor is capable of providingДay: why does an inductor create a voltage spike? Loshki: in australia, theres a whole scale, from yuppy food to fapworthy

When the mosfet opens, the main power supply is still 5V (as designed) and the current is still 1A (because the inductor resists current changes) but now the voltage across the inductor rises to +5.7V, so that the supply & inductor in series can push current through to the output cap CuriousIntheUKДЄnd say the output capacitor voltage is presently 10V Viper-7: Are there units of wank? Just wondered. So your main power supply is supplying 5V and the current is 1A and the mosfet is closed the inductor also has 1A through it and -5V across it (because none of those other components are presently doing anything), right? Rhen u deep dive on dem network topologies It will stay the same when it's closed and when it's openДay: are you aware power supplies can be connected in series? Well most have a certain input voltage rangeДay: the power supply voltage doesn't change because the mosfet opened Immibis: and that cant do damage in any way?Дuring discharge, the - of the inductor is Vin, thats what i meant by 'in series with Vin'Дay: power supplies are designed for current to go through them. Day: the current goes through the power supply
