The MAX17126B generates all the supply rails for thinfilm transistor liquid-crystal display (TFT LCD) TV panels operating from a regulated 12V input. They include a step-down and a step-up regulator, a positive and a negative charge pump, an operational amplifier, a highaccuracy high-voltage gamma reference, and a highvoltage switch control block. The device.
high output current (Q200mA), fast slew rate (45V/Fs), wide bandwidth (20MHz), and rail-torail outputs. Also featured in the device is a high-accuracy, highvoltage adjustable reference for gamma correction. The device is available in a small (7mm x 7mm), ultra-thin (0.8mm), 48-pin TQFN package and operates over the -40NC to +85NC temperature range. LCD TV Panels Applications Features S 8.0V to 16.5V IN Supply Voltage Range S Selectable Frequency (500kHz/750kHz) S Current-Mode Step-Up Regulator Fast Load-Transient Response High-Accuracy Output Voltage (1.0%) Built-In 20V, 3.5A, 100mI MOSFET .
