SWITCH NODE
The switch node is the noisiest place in the switcher circuit with
large ac and dc voltages and currents. This node should be wide
to minimize resistive voltage drop. To minimize capacitively
coupled noise, the total area should be small. Place the FETs
and inductor close together on a small copper plane to minimize
series resistance and keep the copper area small.
GATE DRIVER PATHS
Gate drive traces (DH and DL) handle high dI/dt and tend to
produce noise and ringing. They should be as short and direct
as possible. If vias are needed, it is best to use two relatively

optimal, slowing down the gate drive slightly can be helpful to
reduce noise and ringing. It is occasionally helpful to place
small value resistors, such as between 2 Ω and 4 Ω, on the DHx
and DLx pins. These can be populated with 0 Ω resistors if
resistance is not needed. Note that the added gate resistance
increases the switching rise and fall times, as well as increasing
switching power loss in the MOSFET.
OUTPUT CAPACITORS
The negative terminal of the output filter capacitors should be
tied close to the source of the low side FET. Doing this helps to
minimize voltage differences between AGND and PGNDx.
large ones in parallel to reduce the peak current density and the
current in each via. If the overall PCB layout is less than
