SM4801規(guī)格書詳情

描述 Description

The SM4801 integrates one synchronous AVDD boost converter, a low dropout LDO, a VGH synchronous boost converter, two synchronous buck converters, two VGL negative charge pumps, a 7-bit VCOM calibrator, a high performance VCOM OP amp with temperature compensation, a gate pulse modulator (GPM) and a voltage detector. The AVDD boost converter provides the regulated supply voltage for the panel source driver ICs while the VGH boost converter provides the regulated voltage for the positive level shifter supply which can vary according to the temperature sensed by an external NTC thermistor. The negative charge pump regulators provide the negative voltage for the negative level shifter supply, and two buck converters and an LDO regulator to supply the system’s logic voltage. The gate pulse modulator modulates the output voltage of the level shifter. The highspeed op-amp is designed to drive the LCD backplane (VCOM) with the capability of high current and wide bandwidth. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications.?
