Output Voltage Ripple
The EVM CCM output voltage ripple is shown in
. 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 output capacitors.
The DCM output voltage ripple is shown in
. The output current is 0.1 A and V
IN
= 12 V.
The Pulse Skip Eco-mode™ output voltage ripple is shown in
. There is no external load on the
output and V
IN
= 12 V.
