2.5 Output Voltage Ripple
The EVM continuous conduction mode (CCM) output voltage ripple is shown in Figure 7. The output
current is the rated full load of 2 A and V
IN
= 9 V. The voltage ripple is measured directly across the output
capacitors.
The discontinuous conduction mode (DCM) output voltage ripple is shown in Figure 8. The output current
is 0.15 A and V
IN
= 9 V.
The pulse skip mode output voltage ripple is shown in Figure 9. There is no external load on the output
and V
IN
= 9 V.
