Inverting buck-boost topology
A buck-boost arrangement whose output polarity is opposite to its defined input reference.

What it represents
A buck-boost arrangement whose output polarity is opposite to its defined input reference.
On a schematic, identify the switch/inductor path, input return and negative-output reference and trace the energy-transfer and feedback circuit. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Negative output polarity distinguishes this arrangement from a non-inverting four-switch buck-boost stage.
The preview is a conceptual topology reference rather than a complete power-stage circuit. Switching sequences, magnetic design, component selection and control/protection details belong in the equipment design documentation.
How to read it
- Identify the switch/inductor path, input return and negative-output reference.
- Trace the energy-transfer and feedback circuit.
Information to show or reference
- Label the switch/inductor path, input return and negative-output reference.
- Cross-reference the energy-transfer and feedback circuit.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
Negative output polarity distinguishes this arrangement from a non-inverting four-switch buck-boost stage.
