3 Hardware Overview
Figure 2 illustrates a LED lighting system running from DC power.
Figure 2. Lighting System Topology
There are multiple ways of controlling LEDs. This board uses the C2000 devices to control a separate DC
supply for each of the LED strings. Brightness control is accomplished using the C2000 devices by
independently varying the output power of each DC/DC stage. This allows the user to control the average
current passing through each LED string. Since average current is roughly proportional to lumen output,
each LED string’s brightness is controlled. Figure 3 shows the circuit diagram for the LED BoosterPack.
