Part Number: LM5117 The setup is inputting 40V and outputs 40V without load. with a 4owatts load, the voltage drops to 39V.
I have tried to adjust the values at Rfb2 and Rfb1 to obatina a change on the output and all this has not been able to yield any…
Part Number: LM5117 Hello support team,
My customer has experienced the rebooting issue because of the UVLO of LM5117.
The voltage divider would be 54.9K/11.3K at UVLO pin where input voltage will be the minimum at 8.5V.
Because the minimum voltage is…

Hi,
I purchased a LM5117EVAL board recently. You can see the schematic from page 10 in this datasheet (chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/ www.ti.com/.../snva466b.pdf
Below is the Iout vs Vout plot from 1A to 9A, step…

Hello Nasser
Please confirm the maximum input voltage.
Please connect AGND and PGND at the DAP/EP.
Yes, there is a risk. If you can, please consider heat-sink on both sides.

Hi Aurora,
Thanks for the support. Yes, VCCDIS is floating now, I cut the wire.
All LM5117 have the issue that Vout is correct when no load, but drops to 0V when connecting to a load.
Only U6 could draw max 0.2A current.
Part Number: LM5117 Hi,
I need the support on this component LM5117QPMH/NOPB.
When i am simulating Power integrity. we are taking the out put current of 14Amps.
The IC Pin and Trace are getting highly affected with max current density 315mA/mil2. We tried…

Hi,
I'm designing a Input=48V, output=36V, 0.7A buck circuit with LM5117. I got the schematic design from webench.
I build the same circuit in PSpice for TI. However, it failed to converge. Auto-converge is enabled. Any idea…
