The only limitation in the BATT range is the inability to generate more than 5 times, or less than 1.15 times the BATT voltage at OUT. This is due to PWM controller duty-cycle limitations in Run Mode. Minimum start-up voltag ...

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.
