• ### LT3580 voltage overshoot

Hi,

In my design I am planning to use LT3580 but I have the following issue: When the simulation starts, although the Vout is set to ~33V, the output voltage starts from ~39V. This is not a behavior that the following powered device will be accepting…

• ### LT8335 vs. LT3580

In my design I need 2 supply rails +12V & -12V from a +5V. I will be using these supplies to power transceivers that are rated a max current drawn of 120mA\130mA. In order to give enough spare in the power ratings of the required solution I thought of…

• ### LT3580 maximum duty cycle

Hi,

I have a question regarding the maximum duty cycle (DCmax) calculation given on page 8 of the LT3580 datasheet.

I think Tp here means is the inverse of fosc, which is defined on page 12.

If so, for a given fosc = 1 MHz one obtains RT = 90.9 kOhm…

• ### Faied to output -15V using LT3580

Hi everyone,

It looks like that it doesn't let me to upload .asc simulation file, so I just take a snapshot, sorry about the inconvenient.

So I was trying to output -15V from LT3580 with 15V input. Could anyone help me to check whether this design…

• ### Problem with driving a circuit using boost converter(LT3580) from Li-ion Battery

Hi All,

I have a device that runs on 9V battery. It consumes about 100 mA @ 8.5 V. I am trying to replace 9V battery with rechargeable Li - ion battery (1 cell nominal 3.7 V). I have connected Li-ion battery to input of LT3580 (schematic attached). The…

• ### 负输出稳压器

如图为原理图，现在的情况就是在实际的调测中，LT3580不工作，SW也没有输出波形，请教一下有什么解决办法？

• ### RE: LT8580 Frequency Foldback

If this part uses the same control circuit as the LT8580, or LT3580, I would expect the same behavior.
