The inductor value and inductor switching frequency have the greatest impact on the output brightness and current
consumption of the EL driver. Figures 4 and 5 show the dependence of brightness and current draw of a D381A circuit
on coil values and CHF values for two sample EL lamps sizes and input voltages. The CLF value was chosen such that
the output voltage did not exceed 220Vpp. Please note that the DC resistance (DCR) of inductors with the same nominal
inductance value may vary with manufacturer and inductor type. Thus, inductors made by a different manufacturer
may yield different outputs, but the trend of the different curves should be similar.
