illustrates the basic circuitry in boost topology, which allows
supplying string up to eight LEDs up to 150 mA
consumption. Table 3, Bill of Materials shows the small
number of additional parts which are necessary to assembly
mentioned demoboard. The demoboard based on one layer
PCB and the layout is shown in Figure 23, Buck Demoboard
Layout. The photo of this demoboard is mentioned in
Figure 24, Boost Demoboard Photo. Figure 26, Dimming
Characteristic shows behavior of circuitry in case the square
wave signal with 5 V amplitude and 300 Hz frequency was
delivered into ON/OFF pin of device. There was tested eight
