Figure 17. Buck Demo Board with External Switch Application Schematic
This design illustrates the NCP3065 being used as a PFET
controller, the design has been optimized for continuous
current operation with low ripple which allows the output
filter capacitor to be eliminated. Figure 20 illustrates the
