7.7 Non-overlap time
The inherent glow time of cold-started CFL lamps reduces the switching lifetime of the
electrodes. To make this glow phase as short as possible, the maximum power is given to
the lamp during the glow time via a special control. See
The non-overlap time is defined as the time when both MOSFETs are not conducting. The
non-overlap time is fixed internally.
