Application information
L6585D

5.1.3
Run mode (time interval C Figure 5)
As the voltage at EOI exceeds 1.9V and the lamp has ignited, the L6585D enters Run mode
and remains in this condition unless one of the protections (all enabled in this mode) is
trigged.
The switching frequency reaches the FRUN value set by RRUN and COSC:
