E522.32 Demoboard 2 x Boost-to-Battery AN 0158 Headlight LED
... The LED string is protected against over voltage by the over OVP voltage divider for each channel. The OVP threshold is adjusted to approx. 60V on the 1st channel ( Low- and High-Beam) and approx. 50V on the 2nd channel (Daytime Running Light). That means, an output voltage of > 60V at the 1st chann ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
