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.
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.
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.
The drawback is the output voltage in most cases cannot be adjustable and less than 300mA maximum output current. An inverter converter can output large current and only requires one inductor. The circuit is simple but the drawback is the input and the output must have good filters to obtain good performance.
