What IC is used for a negative voltage inverter?The supplier’s Application Note 782 3 illustrates a negative voltage inverter using the MAX1681. Another Application Note (3659 4) from Maxim presents a charge pump converter circuit that produces -10 V at no load with more than 200 mA from +5-V input. The charge pump IC used in this circuit is MAX889 as shown in Figure 4.
How to generate a negative output voltage from a positive input voltage?In order to generate a negative output voltage from a positive input voltage, the designer would usually opt for the buck-boost topology or possibly a SEPIC converter, both of which offer reasonable efficiency that is much higher than a linear regulator. However, the same outcome can be reached with a buck 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 .
Can a cot converter have a negative output voltage?The COT converters can also be configured in a buck-boost topology, allowing for a negative output voltage. This application note looks at the SiP12116 configured as a negative output buck converter. The buck topology is conventionally used to convert a larger bus or system voltage into a smaller voltage.
