2. Route the traces outlined in bold with wide PCB traces.
3. Place a 1-
F 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 100-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
.
8. Use short traces for the charge pump drive pin (DRVN) of VGL because the traces carry switching
waveforms.
9. Place the feedback resistors of the negative charge pump away from the DRVN trace to minimize coupling
10. Place the flying capacitors as close as possible to the C1P, C1N and C2P, C2N pin.
11. Solder the PowerPad of the QFN package to GND and use thermal vias to lower the thermal resistance.
12. A solid PCB ground structure is essential for good device performance.
The power pad is the analog ground connected to the internal reference
Pin 32, 33 are the power grounds for the boost converter Vs
Pin 5 is the power ground for the step-down converter Vlogic and internal digital circuit
Pin 6 is the power ground for the negative charge pump VGL
Pin 14 is the power ground for the positive charge pump POUT
Pin 37 is the analog ground for the internal reference
13. For more layout recommendations, see the TPS65167 evaluation module (EVM)
