PCB Layout Guidelines
Efficient PCB layout is critical for stable
operation. For optimal performance, refer to
Figure 6 and follow the guidelines below.
1. Place the input MLCC capacitors as close
to VIN and PGND as possible.
2. Place the major MLCC capacitors on the
same layer as the MPQ8634B.
3. Maximize the VIN and PGND copper plane
to minimize parasitic impedance.
4. Place as many PGND vias as possible as
close to PGND as possible to minimize both
parasitic impedance and thermal resistance.
5. Place the VCC decoupling capacitor close
to the device.
6. Connect AGND and PGND at the point of
the VCC capacitor’s ground connection.
7. Place the BST capacitor as close to BST
and SW as possible with 20 mil or wider
traces to route the path. It is recommended
to use a bootstrap capacitor of 0.1μF to 1μF.
8. Place the REF capacitor close to TRK/REF
to VSNS-.
9. Place via at least 10mm away from the
positive side of the first input decoupling
capacitor close to the IC if it must be placed
on the PGOOD pad.
10. Place the OSENSE capacitor in between
the output sense lines and close to the
device.
