4.3.2 Inverter
4.3.3 Inverter current wave
Note1: Luminance control frequency indicate the input pulse frequency, when select the external pulse
Note2: The power supply lines (VDDB and GNDB) have large ripple voltage (See "4.3.4 Power

supply voltage ripple".) during luminance control. There is the possibility that the ripple
voltage produces acoustic noise and signal wave noise in audio circuit and so on. Put a
capacitor (5,000 to 6,000μF) between the power supply lines (VDDB and GNDB) to reduce the
noise, if the noise occurred in the circuit..
