TFT-LCD Power-Supply Controllers

General Description

Features

♦ 2.7V to 5.5V Input Supply Range

♦ Input-Supply Undervoltage Lockout

♦ Current-Mode Step-Up Controller

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.

♦ Linear-Regulator Controller for Logic Supply

♦ High-Performance Buffer Amplifier (MAX1513 Only)

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.

Ordering Information

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.
