SUNNYVALE, CA-January 29, 2004-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX8710/MAX8711/MAX8712/MAX8761, linear-regulator, power-supply solutions for thin-film transistor (TFT), liquid-crystal display (LCD) panels used in LCD monitors and LCD TVs. Each device includes a high-performance AVDD linear regulator, a positive charge-pump regulator, a negative charge-pump regulator, and built-in power-up sequence control. The MAX8710/MAX8711 include a high-current operational amplifier. Additionally, the MAX8710 provides logic-controlled, high-voltage switches to control the positive charge-pump output.
The linear regulator directly steps down the input voltage to generate the supply voltage (AVDD) for the source driver ICs. The two built-in charge-pump regulators are used to generate the TFT gate-on and gate-off supplies. The high-current operational amplifier is typically used to drive the LCD backplane (VCOM) and features high output current (150mA), fast slew rate (7.5V/µs), and wide bandwidth (12MHz). Its Rail-to-Rail® inputs and output maximize flexibility.
The MAX8710 is available in a 24-pin TQFN package. The MAX8711 is available in a 16-pin TQFN and the MAX8712 in a 12-pin TQFN package. Each package is 4mm x 4mm with a maximum thickness of 0.8mm for ultra-thin LCD panel design. These controllers operate over the -40°C to +100°C temperature range.
Prices start at $3.62 for the MAX8710, $3.52 for the MAX8711, and $3.37 for the MAX8712 (1000-up, FOB USA). To speed designs, a preassembled evaluation kit for the MAX8710 is available with recommended external components.
