... 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 ...
