ADVANCE INFORMATION for pre-production products; subject to change without notice.
Continuous Conduction Mode (CCM) operation is employed when the load current is higher than a half of the peak-to-peak inductor current. If the load current is decreased, the part enters DCM mode. In CCM operation, the frequency of operation is constant and fixed unless the minimum tON_MIN or tOFF_MIN are exceeded, which causes the part to enter foldback mode. In both these cases, CCM operation is still maintained, but the frequency of operation is folded back (reduced) to maintain proper regulation.
