Switching regulators have delivered such convenience and efficiency compared to their linear siblings, that it’s now becoming rare to see an old-style three-terminal regulator. Modern designs have ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

The messages of conventional wisdom and “rules of thumb” that were perhaps once true can take a long time to change. Consider the widely held view on step-down (buck) switching dc-dc regulators ...

In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...
