TFT-LCD DC-DC Converters with
Operational Amplifiers
General Description
The MAX1516A/MAX1517A/MAX1518A include a high-
performance step-up regulator, two linear-regulator con-
trollers, and high-current operational amplifiers for active-
matrix thin-film transistor (TFT) liquid-crystal displays
(LCDs). Also included is a logic-controlled, high-voltage
switch with adjustable delay.
The step-up DC-DC converter provides the regulated sup-
ply voltage for the panel source driver ICs. The converter
is a high-frequency (1.2MHz) current-mode regulator
with an integrated 14V n-channel MOSFET that allows
the use of ultra-small inductors and ceramic capacitors.
It provides fast transient response to pulsed loads while
achieving efficiencies over 85%.
The gate-on and gate-off linear-regulator controllers pro-
vide regulated TFT gate-on and gate-off supplies using
external charge pumps attached to the switching node.
The MAX1518A includes five high-performance opera-
tional amplifiers, the MAX1517A includes three, and the
MAX1516A includes one operational amplifier. These
amplifiers are designed to drive the LCD backplane
(VCOM) and/or the gamma-correction divider string. The
devices feature high output current (±150mA), fast slew
rate (13V/μs), wide bandwidth (12MHz), and rail-to-rail
inputs and outputs.
The MAX1516A/MAX1517A/MAX1518A are available in
32-pin thin QFN packages with a maximum thickness of
0.8mm for ultra-thin LCD panels.
