To make things easier we have provided frequency graphs for inductance values of 47, 100, and 220 µH. The graphs show how the frequency of the oscillator varies with supply voltage for each LED series combination from 1 to 8 LEDs. For these three conditions the LED current was set to 300 mA using a 0.33 Ω sense resistor. These graphs can be found on pages 8, 9 and 10 of the data sheet.
