ok thanks. i have 2 questions about the scheme 1- if i have a generator that produce about 20v for LCD Backlight(my lcd want 20 v for back light), should i build the back light circut that get 5 volts as input and amplify it to output ?
2-what is the function of the coil BEAD MLB-160808-0600A-N2 (L1) ?
