The MAX8710/MAX8711/MAX8712/MAX8761 offer completelinear-regulator power-supply soluTIons for thin-filmtransistor (TFT) liquid-crystal-display (LCD) panels usedin LCD monitors and LCD TVs. All four devices include ahigh-performance AVDD linear regulator, a posiTIvecharge-pump regulator, a negaTIve charge-pump regulator,and built-in power-up sequence control. TheMAX8710/MAX8711/MAX8761 also include a high-currentoperaTIonal amplifier. Additionally, the MAX8710/MAX8761 provide logic-controlled high-voltage switchesto control the positive charge-pump output.The linear regulator directly steps down the input voltageto generate the supply voltage for the source-driver ICs(AVDD). The two built-in charge-pump regulatorsare used to generate the TFT gate-on and gate-off supplies.The high-current operational amplifier is typicallyused to drive the LCD backplane (VCOM) and featureshigh output current (150mA), fast slew rate (12V/μs), andwide bandwidth (12MHz). Its rail-to-rail inputs and outputmaximize flexibility.The MAX8710/MAX8761 are available in a 24-pin thinQFN package, the MAX8711 is available in a 16-pin thinQFN package, and the MAX8712 is available in a 12-pinthin QFN package. All three packages are 4mm x 4mmwith a maximum thickness of 0.8mm for ultra-thin LCDpanel design. The MAX8710/MAX8711/MAX8712 operateover the -40°C to +100°C temperature range and theMAX8761 operates over the -40°C to +85°C range.ApplicationsLCD Monitor Panel ModulesLCD TV Panel Modules
