I have made a SPICE simulation for converting +12 DC to +5 volts using MC33063
from ONsemi; Cadence Orcad Capture generates the netlist well but
pSpice calculations do not converge. Is there anyone to help the
simulation converge, please? The whole project is attached.
models and schematic are OK. you only have to fix some parameters. Check Skip the initial transient bias point calculation (SKIPBP), then run 20ms with a maximum step size of 1 us. It will work fine.Below the simulation on 10 and 100 Ohm.
