The bootstrap circuit presented here is faster than traditional methods and also turns itself off after startup. The latter feature removes unwanted power dissipation, making it easier for ...

Bootstrap circuits are widely used in dc-dc converters to serve as top-side bias voltage supplies. After explaining how bootstrap circuits work, this article will show how versatile they can be ...

The circuit in this Design Idea bootstraps a large capacitor in series with the solenoid to provide a large actuation voltage (Figure 1). This higher voltage provides substantially more current to ...
