The LP6278includes 19-channel high-voltagelevel shifter. This device is suitable for GOA TFT-LCD panel application. It converts logic level signals from Timing Controller(T-CON) to high level signals used by the LCD panel. The outputs are switching from VGL/LVGL to VGH1/VGH2, with capacitive loads up to 4.7nF.
The LP6278transform the logic-level controlled signals, which are generated by the display timing controller (TCON), into the high-level signals needed by LCD panel.
It provides outputs (STV0, STV1A, STV1B, LC1, LC2, CLK1~CLK12, LS_VGL, LS_LVGL) witchare switching from VGL/LVGL to VGH1/VGH2, it also integrates Terminate function.
The LP6278features extensive protection functions that include UVLO, OTP, SCP and OCP. The deviceoperates over the -40°C to +85°C. It is available in 5mmx5mm, 40-
lead QFN package.
