Figure 29. PCB Layout
1. Place the power components outlined in bold first on the PCB.
2. Route the traces outlined in bold with wide PCB traces.
3. Place a 1-
µF bypass capacitor directly from the SUP pin to GND and from AVIN to GND.
4. Use a short and wide trace to connect the SUP pin to the output of the boost converter Vs.
5. Place a 470-nF bypass capacitor directly from the SUPN pin to GND.
6. Place the 220-nF reference capacitor directly from REF to GND close to the IC pins.
7. The feedback resistor for the negative charge pump between FBN and REF needs to be >40 k
Ω.
8. Use short traces for the charge pump drive pin (DRVN) of VGL because the traces carry switching
waveforms.
