EP-85 6 V, 330 mA Low Cost Charger
04-Oct-2005
10.4.2 Measurement Results
Output ripple measurements were carried out at room temperature. A programmable AC
source was used with line frequency set to 60 Hz. Output ripple measurement recorded
at end of DC harness. Carbon film resistive loads were utilized.
Figure 20 â VO Ripple, 90 VAC / 60 Hz,
VO = 2.5 V.
5 ms & 20 µs, 100 mV / div.
Figure 21 â VO Ripple, 90 VAC / 60 Hz, VO = 6 V.
5 ms & 20 µs, 100 mV / div.
Under worst-case 90 VAC and 265 VAC and maximum loading conditions, total switching
output ripple is below 150 mV pk-pk.
