I'm designing a boost converter to boost 3.3 V to ~25-30 V. I have successfully simulated it in SPICE, but the current draw for converter is enormous - about 8-9 A. How can I handle this nuisance? This is the boost converter circuit I used.
I used \$R_L = 10 \Omega\$ so it doesn't go into discontinuous mode.
I don't need actually any output current, because all I need is to hold a 25-30V potential over a Numitron tube.
I managed to google some versions of this converter featuring MOSFET driver, but failed to understand how they work. Could you please light it up a bit for me?
