Given frequency is switching frequency of GL and GH. Sawtooth frequency on CF pin is twice as high.
Can be set by external capacitor
PWMD is active low: A low level on the PWMD pin corresponds with lamps-on. Example:
means PWMD is during 20 % of each cycle low and the lamps are 20 % of the time on, resulting in a light
output of 20 %.
