MAX1518B fiche technique
MAX1518B
EVALUATION KIT AVAILABLE
TFT-LCD DC-DC Converter with
Operational Amplifiers
General Description
The MAX1518B includes a high-performance step-up
regulator, two linear-regulator controllers, 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
supply 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
provide regulated TFT gate-on and gate-off supplies using
external charge pumps attached to the switching node. The
MAX1518B includes five high-performance operational
amplifiers. These amplifiers are designed to drive the LCD
backplane (VCOM) and/or the gamma-correction divider
string. The device features high output current (±150mA),
fast slew rate (13V/μs), wide bandwidth (12MHz), and
rail-to-rail inputs and outputs.
The MAX1518B is available in a 32-pin thin QFN package
with a maximum thickness of 0.8mm for ultra-thin LCD
panels.
