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 ...

Some systems, such as optical networks, require more than one negative voltage. A common procedure is to boost the main negative supply of –5V to –10V and then reduce it with a linear regulator to –9V ...

Negative voltage sources are widely used in various applications such as computing systems, liquid-crystal display (LCD) source drivers and audio amplifiers Zach Zhang, Staff Applications Engineer, ...

Frequently, the use of a hysteretic regulator is preferred because of its simplicity of use and wide input-voltage range. For example, National Semiconductor's LM5007 is a constant-on-time variation ...

There comes a time in every hardware hacker’s career during which they first realize they need a negative voltage rail in their project. There also comes a time, usually ~10ms after realizing this, ...
