• LT3086 as Adjustable Voltage Controlled Current Source: Low load behaviour

    Hi,

    I want to use the LT3086 as a voltage controlled current source. Based on https://www.analog.com/en/design-center/reference-designs/circuit-collections/lt3086-adjustable-voltage-controlled-current-source.html#cc-overview I realized the following circuit…

  • LT3086 and LT3091 as post switching regulators. Can anyone check my schematic?

    Hello to all,

    I'd like to us these devices to get +/-12V. Hence it is my first design, if someone can check my schematic, it would be appriciated. I can send it via e-mail.

  • [LT3086] As an adjustable current source, heats up at low load conditions

    Dear Analog team,

    I'm currently testing the lt3086 as an adjustable current source.

    I added a few op-amps to convert voltage levels to my ADC / DAC that monitors and controls the device. Appart from that, everything is quite default. (please check…

  • RE: Max junction temperature (Tjmax) for LT3086MPFE#PBF - Regarding

    I will ask the design group to review this post and I will post any significant corrections.

    The LT3086 only has one internal temperature protection threshold - around 165 deg. C.  The 165 deg. C threshold is referenced in the LT3086 datasheet TEMP pin…

  • RE: Internal reference accuracy of LT3086MPFE#PBF

    Thank you for the post.  I will forward this post to the design group and update my post with any additional information that I receive.

    From my understanding, the LT3086 is essentially +/-2% accurate over everything.  That is what I believe is meant when…

  • RE: LTC3649 datasheet circuit fails when powered with load

    Hello,

    As Dong Mentioned, it would be much easier to debug this circuit by testing the LTC3649 by itself.  To do this, Tie the LT3086 SHDN\ pin to GND.  Then, set R8 to various different values to set various output voltages between 0V and 28V.  Look for…

  • LT3959 configuration

    Hello I have a circuit which requires 10V DC supply. However, I have only 5V DC input and I am planning to use LT3959 for 5V to 12V conversion with SEPIC configuration and than use LT3086 LDO for converting it to cleaner 10V DC. Is it meaningful? if not…

  • 请问以下的芯片thermalpad 是否需要加过孔到gnd层呢,还是直接在top层直接连接到地网络

    目前用到以下的电源芯片,请问以下的芯片thermalpad 是否需要加过孔到gnd层呢,还是直接在top层直接连接到地网络:

    如果在thermalpad 上打过孔,应该打几个

     LT3042 : 封装是12-Lead Plastic DFN (3mm × 3mm)

     LT3650 : 封装是10-Lead Plastic DFN (3mm × 3mm)

  • RE: How to set the current limit of an LT3081 using a DAC?

    Regarding a digital potentiometer, the AD5272-20 is a 20kohm digipot (I2C) with 10-bit resolution (1024 steps). You could put it in parallel with a fixed resistor to adjust the range and resolution of the net resistance on the I_LIM pin.

    Regarding using…
