to an external inductor, rectifier, and filter capacitor. This
step-up converter generates the gate-drive voltage, V
required by the internal gate driver circuits. Although there is
some latitude in selecting the values for the external
component, care must be taken that V

instantaneous switching currents, which may damage the
device.
