11 / 16 page  Jul16-07 RevP SP7686: 500mA LED Driver 2007 Sipex Corporation - 11 - The SP7686 can be used with multiple LEDs in parallel as shown below. For best performance, the LEDs should be in a single package, preferably from a single die to have better matching for forward voltage VF for a given forward current IF. In practice, if the VF of one LED is higher than the others, it will consume a larger IF, which will raise its temperature which will then cause its VF to reduce, correcting the imbalance. The overall current will be the sum of the individual currents, for example ITOTAL = 4*ILED. Figure 23. SP7686 with 4 LEDs in parallel Figure 24.
