6 Output Voltage Ripple

Output ripple voltage shown in the following figures is for a single output (ISO OUTPUT 1), V_INP = 5 V, V_ISO = 5 V, P_OUT = 500 mW. The 25-kHz, low-frequency modulation in Figure 6-1 is a result of the UCC12050 spread spectrum modulation (SSM) used to reduce the EMI peak harmonic content.

Figure 6-1 V_ISO1 (5 V) Modulated AC Ripple Voltage About 60 mV, 25 kHz

Figure 6-2 V_ISO1 (5 V) High Frequency, AC Ripple Voltage About 35 mV, 16 MHz
