The input reflected ripple is measured with a current probe and oscilloscope. The ripple current is the current through a 12∝H differential mode inductor, Lin, with esr ≤ 10 mΩ, feeding a capacitor, C1, esr ≤ 700 mΩ @ 100kHz, across the module input voltage pins. The capacitor C1 across the input shall be at least one 220∝F/100V electrolytic capacitor along with two 1uF to 2.2uF/100V ceramic capacitors. Two 220∝F/100V electrolytic capacitors and two 2.2uF/100V ceramic capacitors are recommended. A 220∝F/100V capacitor for C0 is also recommended.
The output ripple measurement is made approximately 7 cm (2.75 in.) from the power module using an oscilloscope and BNC socket. The capacitor Cext is located about 5 cm (2 in.) from the power module; its value varies from code to code and is found on the electrical data page for the power module of interest under the ripple & noise voltage specification in the Notes & Conditions column.
