SLVU276A February 2009 – October 2021 TPS54332
At light load currents, the TPS54332 is designed to operate in pulse skipping Eco-mode. When the peak inductor current is lower than 100 mA typical, the device enters Eco-mode.
Figure 2-10 shows Eco-mode operation, channel 1 (C1) shows the output voltage while channel 2 (C2) shows the switching node (PH).
