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.
