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 ...

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 ...

The circuit in Figure 1 takes advantage of the 1.8-V power supply to provide a delayed Enable for the 3.3-V MOSFET. Synchronous buck controllers use a bootstrap circuit to drive the high-side MOSFET.

The gate driver has been configured with a synchronous FET bootstrap circuit featuring the 100 V, 2800 mΩ EPC2038 eGaN FET, which eliminates the driver losses induced by the reverse recovery of ...
