What is an inverting switching converter?

However, some specific electronic circuits require power sources with the negative voltage at the output side. The inverting switching converter is a DC/DC converter type that enables the supply of negative voltage. Most basic DC/DC converter topologies can be modified to function as inverting converters.

Can a DC-DC converter use a negative voltage rail?

The converter has its I/O’s pin referenced to its lowest voltage potential, which in this case, is the negative output voltage, not the system ground (GND). When using negative voltage rails, designers need to implement level shifter circuits for the system MCU to communicate with the DC-DC converter.

What happens if a DC-DC converter is negative?

When a negative DC-DC is used, communication to the system controller is not trivial. The converter has its I/O’s pin referenced to its lowest voltage potential, which in this case, is the negative output voltage, not the system ground (GND).

How many negative output dc-dc converters are needed?

Again, for simplicity, only one negative output DC-DC converter is shown here, but the principle applies to systems with multiple negative voltage rails or with a mix of both positive and negative voltage rails. One level shifter is needed per I/O pin of each negative output DC-DC converter.

How do you implement an inverting converter?

The implementation of an inverting converter can be accomplished in many ways. It could be by negative referencing, that is, turning a positive voltage to a negative voltage using any buck device. It could also be by positive referencing, turning a negative voltage into a positive voltage by utilizing any boost device .

What is polarity Inverting buck-boost converter?

The inverting switching converter is a type of DC/DC converter that enables the supply of negative voltage. The inverting topology typically uses a single inductor and does not require any coupling capacitor. Polarity inverting buck-boost converter is a simple and low-cost polarity inverting converter with very few power stage components.
