PCB Layout Guidelines
There are only three external components: the inductor and
the input and output capacitors. For any buck switcher IC,
including the FAN5361, it is important to place a low-ESR
input capacitor very close to the IC, as shown in Figure 41.
The input capacitor ensures good input decoupling, which
helps reduce noise appearing at the output terminals and
ensures that the control sections of the IC do not behave
erratically due to excessive noise. This reduces switching
cycle jitter and ensures good overall performance. It is
important to place the common GND of CIN and COUT as close
as possible to the FAN5361 C2 terminal. There is some
flexibility in moving the inductor further away from the IC; in
that case, VOUT should be considered at the COUT terminal.
