Figure 24: PI2127 in high side +48V application, VC
is biased through constant current circuit.
Layout Recommendation:
Use the following general guidelines when designing
printed circuit boards. An example of the typical land
pattern for the PI2127 is shown in
Figure 25:
• Make sure to have a solid ground (return) plane to
reduce circuit parasitic.
• 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 as shown in Figure 25.
• Use 1oz of copper or thicker if possible to reduce
trace resistance and reduce power dissipation.
