The benefits of this RC filters are the reduction of inrush current by approximately 27dB and reflected ripple attenuation by 8dB. The penalty for the hot pluggability and the RC filter is 1% to 2% reduction of the converter's efficiency. See Figures 4 and 5. ! 90mA peak-to-peak " 1) CH1 100V 2.5S 2) CH2 50mV 2.5S FIGURE 4A.
