MAX1513, MAX1514 TFT-LCD Power-Supply Controllers

The MAX1513 MAX1514 provide complete power-supply solutions for active-matrix thin-film Transistor (TFT) liquid-crystal Displays (LCDs). Both devices include a high-performance Step-up Regulator controller, three linear- Regulator controllers, and an adjustable delay block for startup sequencing. The MAX1513 includes an additional linear-regulator controller and a high-performance 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 regulated outputs.
The Step-up Regulator controller drives an external N-channel MOSFET to generate the regulated supply voltage 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 limits the input surge current during startup.
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 create a low-voltage Logic supply. The gamma linear-regulator controller of the MAX1513 CAN be used to generate a gamma-correction reference supply or another generalpurpose supply rail. The MAX1513 's high-performance Buffer Amplifier CAN drive the LCD Backplane (VCOM) or the gamma-correction divider string.
The MAX1513 MAX1514 are available in 4mm x 4mm 20-pin thin QFN packages with a maximum thickness of 0.8mm, suitable for ultra-thin LCD panel design.
