Note 3. The Charge Pump circuit doesn’t work well, if the sync chip clamp voltage input to VIN pin isn’t within this voltage
range. This sync chip clamp voltage is the voltage from the pedestal voltage
Note 4. The measurement point is the point A in Figure 2
Note 5. The reference signal is the 100% white signal.
