PCB Layout Guidelines
(Continued)
11. VLIN5 pin decoupling capacitor should be connected to
the local analog ground.
12. Compensation components should be placed close to
the IC, within 1 to 2 centimeters.
13. Channel 3 should use the analog ground, not the power
ground, to avoid potential noise coupling from the
switching channels.
An example of the power stage layout is shown in Figure 22
