Reducing noise on the output of a switching regulator
www.ti.comWhen a single-voltage supply is used to power multiple loads, instead of using one ferrite bead, multiple ferrite beads (one at each load) can improve filtering perfor-mance by reducing the current through each bead. This makes it much easier to find a bead that has a higher AC resistance at the frequency to be eliminated. Figure 9.

Most drivers convert line voltage to low voltage and current from AC to DC, and may also include supplementary electronics for dimming and/or color correction. Currently available LED drivers are typi-cally about 85% efficient, with some improvement projected. Optical Losses
