8.1 Application Information

The TPS656131-Q1 boost converter output voltage, VPOS, and the inverting converter output voltage, VNEG, require external components to set the required output voltages. The valid output voltage ranges are as shown in Recommended Operating Conditions). The passages below show typical application examples with different output voltage settings and guidance for external component choices.
