

For system stability and coupling noise elimination, the

sensitive components and signals, such as control signal

and feedback loop, should keep away from LX node.



For enhancing noise immunity on VCC pin, the

decoupling capacitor must be connected from VCC to

AGND, and the capacitor should be placed close to IC.



The feedback signal path from VOUT to IC should be

wide and kept away from high switching path.



The trace width and numbers of via should be based on

application current to design. Make sure the switching

power supply has great thermal performance and good

efficiency.

An example of PCB layout guides are shown in Figure 8

and Figure 9 for reference.
