Internal-Switch Boost Regulator with Integrated Scan  
Driver, VCOM Calibrator, and Op Amp for TFT LCDs  
MAX710  
General Description  
Features  
The MAX17100 includes a high-voltage step-up regula-  
tor, three high-performance operational amplifiers, two  
linear regulators, two high-voltage switch control blocks  
for gate-driver supply modulation, a digital VCOM cali-  
brator, and six independent scan drivers.  
o 2.5V to 6V Input Supply Range  
o 1.2MHz Current-Mode Step-Up Converter  
Fast Transient Response to Pulsed Load  
High-Accuracy Output Voltage (1%)  
Built-In 20V, 3A, 0.16Ω n-Channel Power  
MOSFET  
The DC-DC converter is a 1.2MHz current-mode step-  
up regulator with a built-in power MOSFET and pro-  
vides 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 cur-  
rents during startup. The step-up regulator provides  
fast transient response to pulsed loads while producing  
efficiencies over 87%.  
Cycle-by-Cycle Current Limit  
High Efficiency (87%)  
o Three High-Performance Operational Amplifiers  
200mA Output Short-Circuit Current  
45V/µs Slew Rate  
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.  
20MHz, -3dB Bandwidth  
Rail-to-Rail Inputs and Outputs  
o Linear Regulator for Gate-On and Gate-Off Supply  
o Two Logic-Controlled High-Voltage Switches with  
Adjustable Delay  
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.  
o Programmable VCOM Calibrator  
7-Bit Adjustable Current-Sink Output  
Serial Interface  
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.  
Nonvolatile Setting Memory  
o Six Independent Level-Shifting Scan Drivers  
o Built-In Sequencing  
o Soft-Start and Timer-Delayed Fault Latch for All  
Regulator Outputs  
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 (mini-  
mum) and can swiftly drive capacitive loads.  
o Thermal-Overload Protection  
o Gate Driver for External Input-Side Series MOSFET  
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.
