Layout Recommendation:
Use the following general guidelines when designing
printed circuit boards. An example of the typical land
pattern for the PI2126 is shown in Figure 20:
 Make sure to have a solid ground (return) plane to
reduce circuit parasitic inductance.
 Connect all S pads together with a wide trace to
reduce trace parasitics to accommodate the high
current input, and also connect all D pads together
with a wide trace to accommodate the high current
output.
 Connect the SP pin to the S pins and connect the SN
pin to D pins outside the SiP as shown in Figure 20.
 Use 1oz copper or thicker if possible to reduce trace
resistance and power dissipation.
 C6 typically is not required, but if addition bypassing is
preferred, Figure 20 shows the appropriate layout for
an extra VC capacitor.
