2.10 Continuous Conduction Mode Operation
When the output current is greater than one half the peak to peak inductor current, the circuit is operating
in continuous conduction mode (CCM). The output voltage, PH node voltage and inductor current for CCM
is shown in Figure 10.

2.11 Discontinuous Conduction Mode Operation
When the output current is less than one half the peak to peak inductor current, the circuit is operating in
discontinuous conduction mode (DCM). The circuit enters DCM when the nominal output current falls
below 0.337 A. The output voltage, PH node voltage and inductor current for DCM is shown in Figure 11
