... Where VFB is the typical value of feedback pin voltage and VOUT is the nominal output voltage. Although increasing the value of Rfb1 and Rfb2 increases efficiency, this also decreases accuracy due to bias currents at the VFB input. Therefore, a maximum value is recommended for Rfb2 of about 15 kΩ . ...

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.
