7.4.3 CCM Mode

Continuous conduction mode (CCM) operation is employed in the LMR516xx-Q1 when the load current is greater than half of the peak-to-peak inductor current. In CCM operation, the frequency of operation is fixed, output voltage ripple is at a minimum in this mode and the maximum output current of 1A or 0.6A can be supplied by the LMR51610-Q1 or LMR51606-Q1 respectively.
