WFP6462
300-Channel 6-Bit Dot Inversion Driver
2.1. Low SVGA Power Dissipation
The WFP6462 provides a very low power dissipation solution of < 300 mW for module electronics (not
including backlight power) for an all black image.
Table 2-2 shows the power dissipation for a typical SVGA system consisting of 8 WFP6462’s and 2 CL-
FP6131’s (to provide 18 voltage references). 60 Hz polarity inversion is assumed, resulting in negligible
power dissipation for charging and discharging the panel capacitance.
