Using a buck converter in an inverting buck-boost topology

converter has a 5-V output at 2 A, while the inverting buck-boost converter has a –5-V output, also at 2 A. Output voltage ripple and switching-node waveforms for the invert-ing buck-boost and buck converters are shown in Figures 3 and 4. Note that the switching-node voltage varies from V IN to V OUT for the inverting buck-boost converter

How to modify a step-down converter to the inverting buck

Using a step-down converter as an inverting buck-boost converter is a valid application use case, supported by numerous reference designs and applications notes. The TPS82130 step-down power module is used as the example, because of its high integration level and simple design.

Making a Voltage Inverter from a Buck (Step-Down) DC-DC

The only differences between the normal step-down application and inverting operation are the labels of the connection points. step-down, buck, inverting, DC-DC Converter, switch-mode : APPLICATION NOTE 3844 Making a Voltage Inverter from a Buck (Step-Down) DC-DC Converter Consequently, the step-down IC is biased only by the input

INVERTING BUCK-BOOST DCDC CONVERTER DESIGN …

A buck-boost converter basically is a combination of a buck and a boost converter. There are normally two switches at the input and two switches at the output. It can either increase or decrease the input voltage. An inverting buck-boost converter has only one switch at the input and one switch or a …

What is a low noise inverting buck converter? – Power

The low-noise inverting buck converter is a voltage inverter – it creates a negative voltage. Because it is an inverting buck converter and not an inverting buck-boost converter, the output voltage (in absolute value) must always be below the input voltage for proper regulation.
