JBT6K49-AS
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
JBT6K49-AS
Power supply IC for TFT LCD Panels
The JBT6K49-AS chip is an integrated circuit (IC) for generating the supply voltages necessary for a TFT LCD
panel driver. When used in combination with the T6K47 source driver and the T6K48 gate driver for TFT LCD
panels, the JBT6K49-AS enables the module set to operate with low power consumption.
A high-speed CMOS process is employed to achieve low power consumption and high-speed operation for the
JBT6K49-AS.
