    • A low voltage LED (Light Emitting Diode) driving circuit operates under low supply voltage to provide stable and reliable control of LEDs. The LED driving circuit includes a switching transistor to turn on or off an output current in the LED. The LED driving circuit also includes a control transistor for controlling the level of the output current. The two transistors are coupled via a node that is maintained at a low voltage to increase the voltage across the switching transistor. The increased voltage across the switching transistor allows faster switching and more stable control over different levels of output voltage. The LED driver also includes circuit components for matching the turn-on times and turn-off times for different levels of the output current.
    • 低电压LED(发光二极管)驱动电路在低电源电压下工作,为LED提供稳定可靠的控制。 LED驱动电路包括用于导通或关断LED中的输出电流的开关晶体管。 LED驱动电路还包括用于控制输出电流电平的控制晶体管。 两个晶体管经由保持在低电压的节点耦合以增加开关晶体管两端的电压。 开关晶体管两端的增加的电压允许更快的开关和对不同输出电压电平的更稳定的控制。 LED驱动器还包括用于匹配不同电平输出电流的导通时间和关断时间的电路组件。
