3.4.5 Current Booster

The current booster is optional and not populated by default, but can be populated as desired to increase the gate drive strength. To use the current booster, install all the DNI components of the current booster circuitry. There is also an RC damper circuit connected to the bases of the current booster circuit. This RC damper circuit helps with the soft turn-off functionality to reduce Vds overshoot during a short-circuiting event.
