APPLICATION INFORMATION
continuous mode
When the converter is delivering heavy loads from low voltage sources, it operates in continuous mode. As
shown in Figure 9, the inductor current does not drop to zero and the ringing is gone from the OUT voltage
waveform.

pulse-skipping mode
At very light load currents, the TPS6734 cannot generate drive pulses sufficiently narrow to maintain regulation
and operate at 170 kHz. Under these circumstances, the converter operates in a pulse-skipping mode, in which
cycles are skipped. In pulse-skipping mode, the waveforms are irregular and the output ripple contains a
low-frequency component that may exceed 50 mV peak-to-peak.
