Hello,

Do you need all three solutions or just the 12V input to -12V output 1.5A?

I would suggest using a micromodule. LTM4651 is an option for this.

Edit: For the (-12V) to ±5V (adjusted output). 0.1A max

ganging up 2 LTC3260 should be able to…

 an LMThat's it. When I use the LTC3260 appear the problems but not with a supply using two linear regulators (LM 317 / 337). When supply is linear all works fine.I will ask for a power supply solution.

Thanks a lot.

Thank you, I will definitely attention this issue.

What About the PM?  Is the LTC3260  adequate?  do you have any better proposals ?

regards, 

G.

Bad CRC samples occured like every 20 s. In the tests and figures above the bad samples were discarded. So yes, the dataset is reliable.

The SPI interface is now stabalized by extra strong drive strength of the SDO. Yet this did not change the high-noise…

一）LTC326x/LT858x/ADP507x/ADP505x，这几个型号重点了解一下呢。

Hi, Karen, I've already used the documents you suggested. My (actual) problem is only the power supply.

I know the schematics for the evaluation board, but they are not specific enough for me, to see how they solved the power supply problem.

I…
