Part Number: TPS65219 Tool/software: Hello E2E forum.
We are in need of an extremely compact power solution for a space-constrained FPGA power delivery stage.
For this, we require ~800mA of current through an LDO*(see below for asterisk). Having a separate…
Part Number: TPS563252 Tool/software: Hi all,
I'm working on a design that involves having an LDO in parallel with a Buck converter for increased light load efficiency
I've been following this app note: https://www.ti.com/lit/ug/tiduaa4/tiduaa4…
Part Number: TPS7A85A Greetings,
first of all, thanks for updating the calculation file for parallel LDOs.
I was trying the latest version but, with the same parameters, i am experiencing large calculation differences compared to the previous version…
Hey Lucia,
Unfortunately, we are stuck with the blank version because the -1 version has too narrow an LDO input voltage. The -2 version has no automatic sequencing.
The idea we are looking at is using 2x TPS65262 in parallel. So LDO1 in parallel with…
Hi Hale,
We have written 2 white papers and 1 software tool on paralleling LDO's using ballast resistors. We are in the process of adding more LDO's to the software tool, and we wish to update this year for the TPS7A52/3/4. You can easily parallel…
Part Number: TPS7A74 Other Parts Discussed in Thread: TPS7A57 , TPS7A54 , TPS7A53 Dear Sirs,
May I use 2 LDOs in parallel to get a double output current?
My customer wants to use 2pcs TPS7A7401 to do such design.
Please help to advise.
Thanks.
Part Number: LP8733 Other Parts Discussed in Thread: AM2434 , Considering using the DP87334 device, which is pre-configured for the Sitara AM2434 SoC. I do not want to have to program/configure it to modify the default settings if possible.
The DP8733x…
Hi Kei,
FYI - we have many LDO's that can provide 1A or higher current. If you would like a recommended alternative, please let me know what the key requirements are and we can make a suggestion.
To answer your question: Yes, the TPS7A87 outputs can…
Hello Paul,
You can ask the customer to follow the circuit from Fig 22 on the datasheet for paralleling this device. Please note that while the theory should work for your application, we have not actually attempted it. We highly recommend that you prototype…
