WebThe MOSFET drive waveforms can be seen in Fig. 3, which are similar to a standard buck converter. The LX voltage is also shown. LX waveforms range from -3.3 V to +12 V, and the majority of the magnitude is from -3.3 V to 0 V when the low-side MOSFET is on. The next trace represents the output voltage -3.3 V. WebIn a buck converter, the MOSFETs act as switches and are ideally either completely on or completely off. The diodes shown are the MOSFET parasitic body ... Because the inductor current is negative, the current must flow through the high-side MOSFET body diode. In Figure 2, this transition corresponds to Phase 4, where the voltage peaks at a ...
