TFT-LCD Power-Supply Controllers
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.
