说明

MAX17103包含一路高性能升压调节器、一路350mA低压差线性稳压器、一路高速运算放大器、一路负压线性稳压控制器以及一路高压电平转换扫描驱动器。该器件经过优化,可用于薄膜晶体管(TFT)液晶显示器(LCD)。

升压DC-DC转换器为面板源极驱动IC提供稳定的电源电压。1.2MHz高开关频率允许使用超小型电感和陶瓷电容。对于源极驱动器的典型脉冲负载,电流模式控制结构能够提供快速瞬态响应。该升压调节器具有可调节软启动和可调节逐周期限流功能。

大电流运算放大器设计用于驱动LCD背板(VCOM),放大器具有大输出电流(±200mA)、高压摆率(50V/µs)、宽带(12MHz)以及满摆幅输入、输出。

低压LDO线性稳压器带有集成的0.8Ω调整管,可提供至少350mA输出电流。输出电压精度在±1%以内。

高压电平转换扫描驱动器用于驱动TFT面板的栅极。三路输出摆幅高达40V (最大值),可以快速驱动容性负载。为降低功耗,两个互补输出在状态发生变化时能够共用充电电荷。

MAX17103采用32引脚、5mm x 5mm、薄型QFN封装,最大高度0.8mm,非常适合超薄LCD面板。
