2.3 ELECTRICAL CHARACTERISTICS
2.3.1 Driving for inverter
2.3.2 Fuses
Luminance control frequency for LCD lamp
Note1: The power supply lines (VDDB and GNDB) occurs large ripple voltage while luminance
Note1: The power capacity should be more than the fusing current rating. If the power capacity is

less than the criteria value, the fuse may not blow, and then nasty smell, smoking and so on
may occur.
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 6,000 F) between
the power source lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the
circuit.
