This power-management tip introduces the two different circuits for a positive-to-negative voltage conversion and a negative-to-positive voltage conversion. However, there are times when a voltage ...

Electronic equipment uses predominantly positive voltage rails for power; occasionally, some negative voltage rails are also used. For this reason, negative (or inverting) output DC-DC converter ...

This circuit is commonly called a negative buck regulator. This regulator can invert and step up or step down the input voltage. As shown in Figure 2, efficiency is greater than 82% throughout the ...

Linear Technology Corporation announces the LT3958, a high input voltage DC/DC converter for boost, flyback, SEPIC and inverting power supply applications. This device operates over an input voltage ...
