Figure 16. Overload Burst Mode
Figure 17. Hiccup Mode Waveforms
The data in Figure 16 corresponds to the waveform in
Figure 17. The Figure 17 shows V_CC, I_CC, I_sense (pin 2) and
V_out (pin 5). V_out (pin 5) in fact shows the envelope of the
output switching pulses. This mode corresponds to an
overload condition.
