PCB Layout Guidelines
There are only three external components: the inductor, input
capacitor, and the output capacitor. For any buck switcher IC,
including the FAN5362, it is important to place a low-ESR
input capacitor very close to the IC, as shown in Figure 26.
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 C IN and C OUT as
close as possible to the C2 terminal. There is some flexibility
in moving the inductor further away from the IC; in that case,
A1 A2
B1 B2
C1 C2
0603
COUT
V OUT should be considered at the C OUT terminal.
