Driver section
The high-side and low-side drivers allow using different types of power MOSFETs (also multiple
MOSFETs to reduce the RDS(on)), maintaining fast switching transitions. The low-side driver is
supplied by VCCDR while the high-side driver is supplied by the BOOT pin. A predictive dead
time control avoids MOSFETs cross-conduction maintaining very short dead time duration (see
The control monitors the phase node in order to sense the low-side body diode recirculation. If
the phase node voltage is less than a certain threshold (-350mV typ.) during the dead time, it
will be reduced in the next PWM cycle. The predictive dead time control doesn’t work when the
high-side body diode is conducting because the phase node doesn’t go negative. This situation
happens when the converter is sinking current for example and, in this case, an adaptive dead
time control operates.
