RTQ6749 是可用 I<sup>2</sup>C 介面进行程式控制的电源管理 IC，内含两个可提供 PAVDD 和 VGH 输出的同步 Boost 转换器、一个可提供 NAVDD 输出的同步 Buck-Boost 转换器、一个生成 VGL 的电荷泵、一个具有 8 位校准器的高性能 VCOM 生成电路和一个重定电压检测器，使用 WQFN-32L 5x5 封装，适合车载液晶显示幕使用。</br>该器件可在 2.5V-5.5V 输入电压范围内工作，其工作频率高，可避免对调幅收音机的工作造成影响。所有转换器都具有电流限制保护、输出故障关机保护和故障时向车载电脑发出故障提示信号的功能，还有可调的软启动可限制启动期间可能造成的电流冲击。建议结面温度范围为 -40°C 至 150°C，环境温度范围为 -40°C 至 105°C。
