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

efficiency with 1 and 2 LEDs and output currents of 350 mA
and 700 mA. Additional data and design information can be
found of this design in Application Note AND8298.
