JBT6K49-AS Datasheet | Toshiba

.. TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic 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 bination 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.
