4.9 Input Voltage Ripple
Figure 9 shows the EVM input voltage ripple at rated full load of 2.1 A at V
IN
= 3.6 V. The ripple is
measured directly across the input capacitor, C2.

Figure 10 shows the EVM input voltage ripple in DCM operation with a 100 mA load at V
IN
= 3.6 V. The
ripple is measured directly across the input capacitor, C2.
