Hello Bartosz,
The LM5123 EVM does not reflect the recommendation that is given in the datasheet. So, I would not recommend copying the layout / placement of the components from that EVM. At least you should move the sense resistor(s) and ceramic input…
Part Number: LM5121 I am seeing failures in a design with the LM5121 when the output drops below the input voltage. I don't yet understand why the component is breaking down and would need help here.
The settings are as follows: Input voltage: 24V…
Part Number: LM5121 Hi team,
Can we provide information about Vcs-th2,3 similar as Vcs-th1, which shows "-40C to 125C" spec and "25C" spec? I think Vcs-th2,3 only defined in "-40C to 125C" spec
Best regards,
Hayashi
Part Number: LM5121 Hi team,
My customer is considering to use this device as a charger. And the function they need is voltage regulation and current limit.
The spec is: the output is 48V and the limit current is 5A.
Support need:
1. Does this device…
Part Number: LM5121 3225.LM5121.pdf
I have used WEBENCH to design a power supply of a class D amplifier. The power supply specification as below:
Input voltage: 11-16V
Output voltage: 47/53.5V (by changing the feedback resistance ratio)
Output current…

Hello Jimmy,
As we did not hear back from you, I expect that the answer was sufficient or you solved your issue yourself. I will close this thread now. If my assumption is wrong, please post below or create a new thread, if this one is already locked…
Part Number: LM5121 To Whom It may concern
Good day,
The datasheet describes EP as having no internal electrical connection, but since it is connected to the chip with Ag paste. Is it correct that EP is connected to GND
<Datasheet P3>
Exposed pad…
Hi Niklas,
The new revision has arrived, but I have yet to test it for long durations.
So far the upgraded disconnect FET hasn't failed after several enables. Even with the motor driver's capacitance added to the input capacitance and input voltages as…
Part Number: LM5121-Q1 We had assemble the board and tested with upto 10A. Initially we got efficiency less than 90%. After the removal of snubber circuit parallel to high side N channel MOSFET, we got efficiency upto 93%. Is there any method such that…
