MAX17117 内置开关的boost调节器，集成7个通道的
max17117内置开关的boost调节器，集成7个通道的扫描驱动器、运算放大器和ldo
the max17117 includes a high-performance step-up regulator, a 350ma low-dropout (ldo) linear regulator, a high-speed operational amplifier, and a high-voltage level-shifting scan driver with gate-shading control. the device is optimized for thin-film transistor (tft) liquid-crystal display (lcd) applications.
the step-up dc-dc converter provides the regulated supply voltage for panel source-driver ics. the high 1.2mhz switching frequency allows the use of ultra-small inductors and ceramic capacitors. the current-mode control architecture provides a fast-transient response to pulsed loads typical of source driver loads. the step-up regulator features an adjustable soft-start and an adjustable cycle-by-cycle current limit.
the high-current operational amplifier is designed to drive the lcd backplane (vcom). the amplifier features high output current (±200ma typ), fast slew rate (40v/µs typ), wide bandwidth (16mhz typ), and rail-to-rail inputs and outputs.
the low-voltage ldo linear regulator has an integrated 0.8ω pass element and can provide at least 350ma. the output voltage is accurate within ±1%.
the high-voltage, level-shifting scan driver with gate-shading control is designed to drive the tft panel gate drivers. its seven outputs swing 40v (maximum) between +35v (maximum) and -15v (minimum) and can swiftly drive capacitive loads.
the max17117 is available in a 32-pin, 5mm x 5mm, thin qfn package with a maximum thickness of 0.8mm for thin lcd panels.
2.3v to 5.5v in supply-voltage range 1.2mhz current-mode step-up regulator fast-transient response high-accuracy reference (1%) integrated 16v, 2a, 200mω mosfet high efficiency (> 85%) adjustable cycle-by-cycle current limit high-performance operational amplifier 200ma output short-circuit current 40v/µs slew rate 16mhz, -3db bandwidth low-dropout linear regulator high-accuracy output voltage (1.0%) high-voltage drivers with scan logic +35v to -15v outputs 40v maximum voltage swing gate-shading control thermal-overload protection 32-pin, 5mm x 5mm, thin qfn package 应用/使用
