A circuit getting 12V and 4A supply which was broken into 2 parts with the help of XL4015 module (converter) which provide 9V and LM2596 module (converter) which provide 5V , further we are using a microcontroller and three L298N to run three stepper motors having same configuration because it was required that we have to run the motor in such a way that it should take small steps (micro steps) at the same time there is a problem that L298N got too heat when this circuit run a time period of 4-5 hours such that our circuit stop working but we required a circuit that can work for 10 hours continuously non stop with a good life cycle. This circuit also give fluctuations at different stages like when 12V was converting in 9V and when 9V was further converting in 5v. In this complete circuit we required at least two 5V connector and a 9V connector so that we can connect our external LED and a fan with it.

Hello, How are you? I think that you have a problem with extra components, let's start to explain it to you: 1. You have three bipolar stepper motors that are powered by L298N from 5 to 12 VDC with a maximum current of 2A each, which adds up to 6A in total. 2. The L298N can power 2 stepper motors at the same time, but I note that you may need them to work separately. So we are not going to change that. 3. The LM2596 gives you 5VDC with a maximum current of 3A. (I don't know what component your power on that) 4. The XL4015 gives you 5VDC with a maximum current of 5A. (I don't know what component your power on that) 5. In the 5V and 9V DC stages gives you fluctuations due to the same reason that you have with the circuit since begin. 6. The source that you have gives you a maximum current of 4A and the stepper motors need 6A or 7A, That is solved with a source from 8A or 10A. With that, it goes away the fluctuations in these stages. In addition, it is possible that you have some extra components and everything could work better for you with fewer components. Sorry, I forgot show you my credentials I am Electronic Engineer and Electronic Technician, I got more than 10 years of working with PCB. I usually use Proteus, Kicad, and more to make my Bakelite designs. Because in the field of electronics it uses a lot. Also, I have many experiences working with different kinds of microprocessors such as stm32, ESP8266, Arduino, PIC, etc.
