Note1: When designing of the power supply, take the measures for the prevention of surge voltage.
Note2: The power supply lines (VDDB and GNDB) have large ripple voltage during luminance
control of LCD lamps. 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.
2.4. FUSE

Note1: The power supply capacity should be more than the fusing current. If it is less than the fusing
current, the fuse may not blow in a short time, and then nasty smell, smoke and so on may
occur.
