RT9907PW - Brand New IC Chips
-
Description
The RT9907PW is an electronic component model in the product category of IC Chips. It is a high-performance integrated circuit designed for use in active matrix thin-film transistor (TFT) liquid-crystal displays (LCDs).
The RT9907PW includes several key components such as a boost regulator, a low dropout linear regulator (LDO), a gate pulse modulator (GPM), a voltage detector, a VCOM buffer, and a VGH charge pump controller.
The boost regulator provides a regulated supply voltage for the panel source driver ICs. It operates at a high switching frequency and achieves efficiency over 90%. The LDO linear regulator can supply up to 350mA current and is suitable for the supply voltage of the timing controller.
The GPM is controlled by frame signals from the timing controller and acts as a flicker compensation circuit to reduce the coupling effect between gate lines and pixels. It also helps achieve a corrected power-on sequence for gate driver ICs. The voltage detector monitors the supply voltage and issues a reset signal if the voltage is too low.
The VCOM buffer drives the LCD VCOM voltage with high short-circuit current, fast slew rate, wide bandwidth, and rail-to-rail inputs and outputs. The VGH charge pump controller provides regulated TFT Gate-On voltage.
