    升压芯片

    升压芯片是什么?

    升压芯片,又称升压转换器,是一种直流到直流电源转换设备。

    升压芯片的工作原理

    • 升压芯片用于增加从输入电源到输出的电压,同时降低电流。电源输入可以来自任何合适的直流电源,例如电池、太阳能电池板、整流器和直流发电机。
    • 升压芯片包含至少两种半导体,例如二极管或晶体管,以及至少一种储能元件,例如电容器、电感器,或者它可以包含两者的组合。
    • 升压转换器能够将能量存储在其电感器中,然后在比开始时输入的负载电压更高的负载电压下同时释放能量,因而在加速设备时非常有用。为了节省电路的功率(因为P=VI),输出电压通常高于输入电压,而输出电流则低于输入电流。

    升压芯片的特点与优势

    • 使用便宜的表面贴装式电感器(因此非常经济高效)
    • 某些型号含有低电池电量检测器
    • 所有设备的效率都很高
    • 一致的峰值电流控制可减少输出纹波
    • 电磁干扰电路

    升压芯片的应用

    • LCD、OLED显示器耗材
    • 移动电话
    • MP3播放器
    • 触觉显示器
    • 便携式设备,如平板电脑
    • PDA
    • 无线系统
    • 条码扫描仪
