2.3.3 Start Up with broken High Side Filament
An open high side filament during the start up hysteresis (10.6V < V
current into the LVS pin 13 or 14 is below I
RES pin 12 rises up to I
The source current is now set to I
controller prevents a power up (see Figure 12), the gate drives of the PFC and inverter stage do not
start working.
When the high side filament is present, e.g. insert a lamp, the current of the active LVS pins exceeds
I
13). Now the controller senses the low side filament. When a low side filament is also present, and the
controller drops (after a short delay due to a capacitor at the res pin) below V
current is set to I
