3.1 DC Regulation in PWM and Power Save Mode Operation

Figure 3-1 DC Regulation of the I2C and the Resistor Divider Version at 12 A Output Current
Figure 3-2 DC Regulation of the I2C and the Resistor Divider Version at 100 mA Output Current

Figure 3-1 and Figure 3-2 show output voltage ripple waveforms at different load conditions. Figure 3-1 shows the output voltage at 12 A load and Figure 3-2 shows the output voltage at 100 mA load. VOUT1 is the waveform of the I2C version and VOUT2 is the waveform of the resistor divider version. Both graphs show no significant difference in output voltage ripple at the different load conditions.
