General Description
The MAX1513/MAX1514 provide complete power-sup-
ply solutions for active-matrix thin-film transistor (TFT)
liquid-crystal displays (LCDs). Both devices include a
high-performance step-up regulator controller, three lin-
ear-regulator controllers, and an adjustable delay block
for startup sequencing. The MAX1513 includes an
additional linear-regulator controller and a high-perfor-
mance buffer amplifier. The MAX1513/MAX1514 can
operate from 2.7V to 5.5V input supplies and provide
overload protection with timer delay latch on all the reg-
ulated outputs.
The step-up regulator controller drives an external N-
channel MOSFET to generate the regulated supply volt-
age for the panel source-driver ICs. Its current-mode
control architecture provides fast transient response to
pulsed loads. The high switching frequency (up to
1.5MHz) allows the use of ultra-small inductors and
ceramic capacitors while achieving efficiencies over 85%
using lossless current sensing. The internal soft-start lim-
its the input surge current during startup.
The gate-on and gate-off linear-regulator controllers of
the MAX1513/MAX1514 provide regulated TFT gate-on
and gate-off supplies. The gate-on supply is activated
after an adjustable delay following the step-up regulator.
The logic linear-regulator controller can be used to cre-
ate a low-voltage logic supply. The gamma linear-regula-
tor controller of the MAX1513 can be used to generate a
gamma-correction reference supply or another general-
purpose supply rail. The MAX1513’s high-performance
buffer amplifier can drive the LCD backplane (VCOM)
or the gamma-correction divider string.
The MAX1513/MAX1514 are available in 4mm
4mm
20-pin thin QFN packages with a maximum thickness of
0.8mm, suitable for ultra-thin LCD panel design.
