Application Schematic illustrates the NCP3066 being used
as a PFET controller. Table 1. Bill Of Materials shows the
small number of additional parts which are necessary to
assemble mentioned demoboard. The demoboard based on
two layer PCB and the layout is mentioned in Figure 16.
Buck Demoboard Layout. The Line regulation is mentioned
in Figure 20, Line Regulation. The Figure 21, 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.
