... When the SENSE voltage across sense resistor RSENSE reaches the threshold voltage, around 0.46 V for lowline condition, the output GATE drive is turned off after a small delay, tPD. This delay introduces an additional current proportional to tPD • VIN / LP. Since the delay is nearly constant, regard ...

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.
