PCB Layout Recommendations
The switching power supply PCB layout needs careful
attention and is critical to achieving low losses and
clean and stable operation. Although each design is
different, below are some general recommendations for
a good PCB layout.
Keep the high-current traces and load connectors
as short and wide as possible. These traces
consist of VIN, GND, VOUT, and SW.
Place the input capacitor, the inductor, and the
output capacitor as close as possible to the IC
terminals.
Keep the loop area between SW node, inductor,
and output capacitors as small as possible;
minimizing ground loops to reduce EMI issues.
Route high-dV/dt signals, such as SW node, away
from the error amplifier input/output pins.
Keep components connected to the FB and COMP
pins close to the pins.
