  • The 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/µS), 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.
  • Ultra-High-Performance Step-Up Regulator: Fast Transient Response to Pulsed Load Using Current-Mode Control Architecture, High-Accuracy Output Voltage (1.3%), Built-In 14V, 1.2A, 0.2Ω N-Channel Power MOSFET with Lossless Current-Sensing, High Efficiency (85%), 8-Step Current-Controlled Digital Soft-Start
  • Two High-Performance Operational Amplifiers: 150mA Output Short-Circuit Current, 7.5V/µs Slew Rate, 12MHz -3dB Bandwidth, Rail-to-Rail Inputs/Outputs, Unity Gain Stable
  • Logic-Controlled High-Voltage Switch with Adjustable Delay
  • Timer Delay Latch FB Fault Protection
  • Thermal Protection
  • 2.6V to 5.5V Input Operating Voltage Range
  • 3.6mA (Switching), 0.45mA (Not Switching) Quiescent Current
  • Ultra-Thin 20-Pin Thin QFN Package (5mm x 5mm x 0.8mm)
