• RE: The Current of VCCS by LT3083 is not stable !

    The internal compensation of the LT3092 is different compared to the LT3083, so that is why the LT3083 is unstable under similar conditions.  The text in the image below from the LT3092 datasheet indicates that the LT3092 may be stable when other LDOs…

  • Disable LT3083

    If I want to disable the device LT3083, Vout=0V, is it enough to set the Vin equals to 0V?

    Should I have to set the Vctrl=0V?

  • RE: RH3083 , Absolute Maximum Ratings, IN Pin Voltage (is it 18 volts or 23 volts)?

    The design group is responsible for the datasheet, but I asked the designer the same question about the similar LT3083 recently and the designer said in that case overload means that the device's current rating is exceeded.  For instance, the LT3083…

  • LT3083 application

    I want to use  LT3083 ,

    1.Vcontrol =18V

    2.Vin = 3--16V,  SET PIN0--15V with DAC output  

    Can I  get  VOUT=0--15V  ?

    thank you !

  • LT3083使能

    第一次使用这个器件,请问如果需要暂时使这个器件不输出,Vout=0V,只需要Vin是0V就行了吗?还是Vctrl也需要置0?

  • 使用LT3083设计恒流源时,电流不稳定问题

    各位大佬好:

            小弟最近在使用LT3083设计一个功率较大(1A级别)的线性LED驱动器,方法是使用DAC输出参考电压Vref,连接到LT3083的Vset引脚,但是在测试时发现LT3083,当LT3083输出电流略大时(30mA),电流就十分不稳定。

    测试条件简述如下:

    1. 供电电源使用DC/DC 或者LDO时,二者测试效果无差别,电流波动大;

    2. 负载使用水泥电阻 或 LED  时,二者测试效果无差别,电流波动大;

    3. 参考电压Vref来源 : 使用DAC8563 或者NI 采集卡USB6009…

  • LT3083使用问题

    我想使用LT3083做一个输出可调的电源,VCTRL固定使用18V,然后把VIN从2V--17V这样调整,SET脚用DAC驱动0-15V变化,这样输出是从0-15来变化,请问这样可以用吗?

    我搭了一个测试板,如果VCTRL用18V,VIN用低压,比如5V,VIN也会被拉高,为什么会这样呢?

  • LT3083电压输出异常

    电路原理图如下(实测电压用红色文本标注):

    Rset实测20K欧,期望输出1.0V,实测0.157V,控制电压,输入电压看上去都正常,请专家帮忙看看是哪里不正确?
