I copied the buck converter in the picture and turned the simulation around.
But the resulting waveform was not what I wanted.
Shouldn't a dc waveform of 7.5V come out? What's the problem
What role do transformers, diodes, resistors, capacitors, etc. play on the MOSFET gate input side, and...
What is the role and purpose of the 470uf capacitor?
Is it simply disconnected because it's connected in parallel with 330uF?
And 5 pin out is 15V pulse or low pulse?
What is the expected transformer ratio?
I am designing a constant 5 volt output switching regulator that bucks 12 to 24 volts down to 5 volts while supporting 5 amps. It is used to boot up a Raspberry Pi with a 10 inch screen. At 12 volts, the Pi will boot up fine. At 24 volts, around halfway through the bootup, the regulator will...
Hey everybody, first time here!
As a personal project I am implementing a Buck Converter simulation in Python. My basic idea is to give a constant Vs supply and simulate the switch on/switch off steps in each switching period, calculate the increase/decrease in inductor current and calculate an...
Hi guys!
I'm working with the power stage for a buck converter, but when I did some measures with the scope I saw thet my inductor current waveform has a thing that I think are ringing spikes. Of course this is not a perfect triangular wave like in simulations hahaha.

Powering a load situated more than 200 meters from the power source will result in huge power loss due to the wires resistance....
The load need 1.5A and the power source can deliver up to 3A max.
Designing a boost converter at the output of the source before connecting it to the wire to step up...
Hi,
I have a question regarding Buck regulator output capacitors via current sharing.
we have 12V to 1V @ 35A regulator design, which uses 7x100uF,5x150uF bulk capacitors, which are placed sequentially few on TOP and remaining are ON BOT layers with vias connecting all capacitors from TOP to...
I want to design a power bank control board for a single-cell lipo battery. The IC I have selected is BQ24195 by texas instruments. I think it is perfect for what I need. It comes with charge control, boost, voltage protection, I2C control, and many other features. But I have some doubts about...
