Figure 9.4 shows the voltage at the DIM pin, the VS (half-bridge) voltage, and the

voltage at the VCO pin during Dim Mode for 100% dimming level. Figure 9.5 shows

these voltages for 10% dimming level.

Figure 9.4: 100% dimming level waveforms: CH1 is the DIM voltage, CH2 is the voltage at VS pin, and

CH4 is the VCO voltage

Figure 9.5: 10% dimming level waveforms: CH1 is the DIM voltage, CH2 is the voltage at VS pin, and

CH4 is the VCO voltage
