trace from load to C OUT should be as short and wide as
possible to minimize trace resistance and inductance. To
minimize noise coupling to load, a small-value capacitor can
be placed between VOUT and C OUT to route high-frequency
noise back to GND before it gets to the load.
Inductor
Inductor (L1) should be placed as close to the regulator as
possible to minimize trace resistance and inductance for the
reasons explained above.
Sense Resistor
The sense resistor provides a feedback signal for the
regulator to control output voltage. A long trace from the
sense resistor to the FB pin couples noise into the FB pin. If
Table 1. Recommended External Components
noise is coupled into the FB pin, it causes unstable operation
of the switching regulator, which affects application
performance. The return trace from the sense resistor to the
FB pin should be short and away from any fast-switching
signal traces. The ground plane under the return trace is not
necessary. If the ground plane under the return trace is
noisy; but not the same ground plane as the regulator; the
noise could be coupled into the FB pin through PCB parasitic
capacitance, yielding noisy output.
As shown in Figure 30; C IN , C OUT , and L1 are all placed next
to the regulator. All traces are on the same layer to minimize
trace resistance and inductance. Total PCB area, not
including the sense resistor, is 67.2mm 2 (7.47mm x
8.99mm) .
