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 6,000mF) between the power supply lines (VDDB and GNDB) to reduce the noise,

if the noise occurred in the circuit.

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.
