Dear all,
I'm working on some project which requires 100v converted from 9v, so i called the basic idea of Boost converter.
The circuit is quiet simple, i use IRF540NS switched from PWM (Pulse Value 3.3v, Pulse Width 278us, Period 300us)
I used TI application note http://www.ti.com/lit/an/slva372b/slva372b.pdf to calculate the values of the coil and the output capacitor using the equations 5,6 and 12, 13.
The inputs are: Vout = 100, Iout(max) = 5mA
After all, L = 148mH and Cout = 511uF
The simulation output is 10v not 100v!!!
Any help please?!
