LCD Panel Step-up Converter With Analog Multi-Function Outputs

The AT1738 offers a complete power-supply solution for TFT LCD panels used in LCD monitors and NB LCD panels. The AT1738 consists of a high-performance Step-up converter, a low-power charge-pump Regulator a high-performance linear Regulator an Operational Amplifier a voltage detector and a logic-controlled gate-on pulse Modulator The Step-up DC-DC Converter provides the regulated supply voltage for the panel source driver ICs. The charge-pump Regulator generates the positive gate-on supply voltage. The operational Amplifier supplies the VCOM Buffer with high output current, fast slew rate and wide bandwidth performances for driving capacitive loads. By Aimtron Technology
