MAX17100 内置开关boost调节器，集成扫描驱动器、
max17100 内置开关boost调节器，集成扫描驱动器、vcom校准器和运算放大器，适用于tft lcd面板
the max17100 includes a high-voltage step-up regulator, three high-performance operational amplifiers, two linear regulators, two high-voltage switch control blocks for gate-driver supply modulation, a digital vcom calibrator, and six independent scan drivers.
the dc-dc converter is a 1.2mhz current-mode stepup regulator with a built-in power mosfet and provides the regulated supply voltage for the panel source driver ics. the built-in power mosfet allows output voltages to be as high as 18v from inputs of 2.5v to 6v. a built-in 7-bit digital soft-start function limits inrush currents during startup. the step-up regulator provides fast transient response to pulsed loads while producing efficiencies over 87%.
three operational amplifiers, typically used as the gamma correction divider string, are configured as unity-gain buffers and feature high output short-circuit current (200ma), fast slew rate (45v/µs), and wide bandwidth (20mhz). their rail-to-rail inputs and outputs maximize application flexibility.
two linear regulators provide regulated gate-on and gate-off supplies for tft panel. the two high-voltage switch control blocks modulate the shape of the gate-on supply with adjustable startup delay.
one operational amplifier is designed to drive the lcd backplane (vcom). it features high short-circuit current of 200ma. the programmable vcom calibrator adjusts the vcom output-voltage level through serial interface by sinking a programmable current from the vcom resistor-divider. the calibrator includes nonvolatile memory cells that store the desired vcom voltage level.
the six independent high-voltage level-shifting scan drivers are designed to drive the tft panel gate lines. the outputs swing from +35v (maximum) to -15v (minimum) and can swiftly drive capacitive loads.
the max17100 is available in a lead-free, 48-pin, thin qfn package with 0.4mm lead spacing. the package is a 6mm x 6mm square with a maximum thickness of 0.8mm for ultra-thin lcd panel design.
