Well finally found the problem. Had a processor pin connected to the temp output on the LT3086. But it was mistakenly configured to be an output at 0 faulting the temp circuit. So the port pin was shorting out the LT3086 chip's temperature output and…
Question from customer about the LT3086:
"Is parallel operation possible on the R- package & if so how?"
Note: Compared to the DHD and FE packages, the R package does not have a TRACK pin so the paralleling method shown in the datashe…
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…
Thank you for the post. The LT3086 demonstration circuit DC1729A is the best reference for this question. According to the DC1729A schematic, TRACK, CDC and TEMP can all float.
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.
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…
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）
LT3091：14-Lead Plastic DFN (4mm × 3mm)
LT3086 : 16-LEAD (5mm…
本人从事煤矿产品的研发与设计工作，在电路设计中用到的电源芯片很多，但Linear的电源管理芯片LT1641-2I和镍氢/镍镉电池充电管理芯片LTC4011使用，让我对Linear产品的品质产生了信心。
众所周知，煤矿产品的最重要的参数是，产品的本安性能，本安性能的确定来自与产品的输入电源。所有的产家都希望自己家的电源输出电压大，输出电流高，带载能力更强，但同时带来的风险是产品的本安性能无法通过测试，容易失爆。在之前的设计中我们为了保护安全性都采用多个稳压管限压，大功率电阻流的方式来保证本安，但这样的设计使得我们牺牲了电源的带载能力…
