PCB Layout Considerations
good load transient performance. Because it is very sensitive
to its PCB layout, particular care has to be taken when
tackling Printed Circuit Board (PCB) layout. The figures
below give an example of a layout where parasitic elements
are minimized. For microprocessor applications it is
customary to use an output capacitor network consisting of
Good PCB layout plays an important role in achieving

several capacitors in parallel. This reduces the overall ESR
and reduces the instantaneous output voltage drop under
transient load conditions. The output capacitor network
should be as close as possible to the load for the best results.
The schematic of NCP565 typical application circuit, which
this PCB layout is base on, is shown in Figure 20. The output
voltage is set to 3.3 V for this demonstration board according
to the feedback resistors in the Table 1.
