2.7 Input Voltage Ripple
The EVM CCM input voltage ripple is shown in Figure 13. The output current is the rated full load of 3.5 A
and V
IN
= 12 V. The voltage ripple is measured directly across the input capacitors.
The DCM input voltage ripple is shown in Figure 14. The output current is 0.1 A and V
IN
= 12 V.
