4.2 Output Voltage Ripple

All converters are operating with an output ripple of 2% or less under full load.

Output ripple was measured at full load (2.43 A). The ripple is around 0.16% of the output voltage.

Output ripple was measured at full load (2.43 A). The ripple is around 0.16% of the output voltage.
