Internal-Switch Boost Regulator and High-Voltage,  
Low-Dropout Linear Regulator for TFT LCDs  
General Description  
Features  
Sꢀ2.5V_to_5.5V_Input_Supply_Range  
The MAX17115 includes a high-performance step-up  
regulator, a high-accuracy, high-voltage, low-dropout  
linear regulator (LDO), a high-performance buffer ampi-  
fier, and a logic-controlled high-voltage switch block.

Cycle-by-Cycle_Current_Limit_  
The DC-DC converter is a high-frequency (1.2MHz/  
640kHz) current-mode step-up regulator with a built-in  
power MOSFET. It provides fast-transient response to  
pulsed loads while producing efficiencies over 88%. The  
built-in power MOSFET allows output voltages as high as  
18V from inputs from 2.5V to 5.5V. A programmable soft-  
start function controls startup inrush currents.

200mA_Output_Short-Circuit_Current_  
45V/µs_Slew_Rate_  
The operational amplifier, typically used to drive the LCD  
backplane (VCOM), features high-output short-circuit  
current (200mA), fast slew rate (45V/Fs), and wide band-  
width (20MHz). Its rail-to-rail input and output maximize  
application flexibility. The high-voltage LDO is adjustable  
and has a high accuracy of Q0.5%. It is typically used to  
drive a gamma reference divider string. The high-voltage  
switch control block modulates the shape of the gate-on  
supply and provides an adjustable delay for power-up  
sequencing.

SꢀBuilt-In_Sequencing  
SꢀThermal-Overload_Protection  
The high-voltage stress (HVS) function is used to tem-  
porarily increase the source-driver supply voltage of the  
LCD panel for aging tests. The HVS digital input controls  
an open-drain internal switch, which is typically used to  
change the feedback divider of the step-up regulator.

The MAX17115 is available in a lead-free, 32-pin, thin  
QFN package. The package is a 5mm x 5mm square  
with a maximum thickness of 0.8mm for thin LCD panel  
design.
