MAX1542, MAX1542ETP, MAX1543 TFT LCD DC-to-DC Converter With Operational AmplifiersThe MAX1542 MAX1543 include a high-performance boost Regulator and two 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 MAX1543 includes an additional High-Voltage load Switch and features pin-selectable boost Regulator switching frequency.
The Step-up DC-to-DC converter is a high-frequency 640kHz MAX1543 /1.2MHz MAX1542 MAX1543 current-mode Regulator with a built-in Power MOSFET that allows the use of ultra-small inductors and ceramic capacitors. It provides fast transient response to pulsed loads while producing efficiencies over 85%. The two easy-to-use, high-performance Operational Amplifiers CAN drive the LCD Backplane (VCOM) and/or the gamma correction divider string. The devices feature high short-circuit current (150mA), fast slew rate (7.5V/s), wide bandwidth (12MHz), and Rail-to-Rail inputs and outputs. The MAX1542 MAX1543 are available in 20-pin thin QFN packages with a maximum thickness of 0.8mm for ultra-thin LCD panel design. By Maxim Integrated Products |
