Technical FAQs 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.

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.

Can a positive-to-negative voltage converter be used for stable outputs?

Linear’s design note 433 entitled “A Positive-to-Negative Voltage Converter Can Be Used for Stable Outputs Even with a Widely Varying Input” 2 describes a design example that shows how to generate negative voltage from a positive input to synchronous step-down controller LT3854.

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 .
