Respected,
I have tried to drive IRFZ44N using 555 timer as per you all suggested. And even got required 19.5V from 3.7V using 33uH Inductor, 22uF capacitor and 68kOHM as the load resistor.
But, when I tried building circuit practically, the inductor got burned (I used inductor of color code orange, orange, black)
And it too effect the IRFZ44N MOSFET. What to do? Why it burned up?
https://postimg.cc/7b0hKtNBhttps://postimg.cc/mPzgFdhNAccording to the suggested calculation of 100KHz, where I need to use 3.9uH inductor, Cout = 330uH I got 10V which is unstable and slowly varying as my output

What to do?
Also, the battery I am using is 3.7V 4000mah battery. Is it the reason?
