Part Number: LM5121EVM Other Parts Discussed in Thread: LM5121 Hi
I am planning to use LM5121 into a new design, would you be able to provide us an altium files that will speed up the design process?.
Thanks.
Andrés.
Part Number: LM5121EVM Other Parts Discussed in Thread: LM5121 hi team,
my customer use our LM5121 EVM to realize 5Vin and 28Vout, but finds the output voltage can only increase to 20.9V, below are the changes they made on our EVM
here is the SW…
Part Number: LM5121EVM Hello, Customer is looking for board dimensions and mounting holes' size and locations. There is no information in the user guide, and there are no design files available. Can you please share information? If 3d/2d CAD files are…
Hi Karthik,
Thanks for the feedback and confirmation.
For these specs, LM5121 is a good recommendation. We have an EVM board available for this device as well. https://www.ti.com/tool/LM5121EVM The default settings for Vout are 12V here, but it can…
Part Number: LM5121 I noticed the diodes proposed by Webench for the freewheeling diode on the disconnection FET circuit seem to be physically huge on our design, unreasonably so (it seems to me).
As a sanity check I put into Webench the parameters…
Part Number: LM5121 The output voltage of LM5121 DEMO board needs 28V, how to set it?
I have adjusted the impedance value of "R27" in the attachment. After the output voltage reaches 20.66V, no matter how much the resistance value is changed, the voltage…
Part Number: LM5121 Hello
My customer have a question following.
Would you please advise?
*** Question***
Q1 UVLO setting p13 eq(1) eq(2) is satisfied in case with external VCC only ?
Q2 also, internal 10uA Hysteresis current source supplied…
Do you mean the LM5122EVM-1PH? We do not have the LM5121EVM-1PH.
From you description your PSU is the problem. At step load response the input current can rise up quickly to provide extra current to meet the output load requirement. This increased…
