Why is my step up converter not increasing voltage and why output is a little lower than input? Answered
My step up converter is not working ,it wont increase the voltage . I used a multi meter and the output ends up being lower than the input like for example when I connected the battery to it, the battery was at 8.40v and I checked the output and it was 8.10v . I was trying to make a DIY speaker for the first time, I am new to this.
step up converter is called a MT3608 LM2577. I got it off of aliexpress.
The battery i used is off a battery pack .it is 8200 mah and 9v
