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…
Hi Austin,
Just want to understand more background that why customer need to parallel LDO and DCDC. Is this mainly to increase light load efficiency or they also have a must requirement for low ripple and low noise?
(1) What is the range of the load current…
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 Chris,
Keep in mind that our newest high performance LDO, the TPS7A57, is rated for 5A without any paralleling.
Yes you can parallel the TPS7A84 and we have customers who are currently paralleling this device already. I would recommend using the updated…
Hi Matt,
Please reply back with any additional questions you may have. Here are the answers to your first questions:
1. Yes, this is completely fine. We have customers that parallel up to 10 LDO's without issue. I'm aware of multiple parallel designs…
Hi Josh,
If you need 2A LDO's, we have options available for you. Just let us know your key requirements (Vin, Vout, Iout, noise, PSRR, etc).
If you still wish to use the TPS7A88-Q1, you can parallel the channels using ballast resistors. We have recently…
