why is there a LC filter at the entrance of the converter? That looks like a noise removal filter. The noise is generated by the 12 volt switching converter (due to high speed switching) on the left and therefore, the LC immediately to its right (its input port) will act as a 2nd order low pass filter and noise/switching artefacts travelling from left to ...

Your voltage error doesn't matter. You're calculating your 5V winding based on the actual number of turns, 17T, so there is no error you have to factor in. Or rather, you already did factor it in. As for the rest, what you're looking for is your volts per turn (\$ V_{pt} \$) ratio based on the winding you intend to use as your regulation voltage. I'm ...

This is the simplest and easiest switching converter to understand: - The input voltage is modulated by the switch's duty cycle to produce an average value that corresponds with the required output voltage. The LC acts as a low pass filter and converts the modulated duty cycle from above into a steady DC value. There are mathematics involved if you want ...
