Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Ratheesh,
It's not a good idea to have vias on the SW node, as it means the high dv/dt node also appears on the other side of the PCB. Better to add vias for the high-side FET drain and allow the inductor to heatsink the low-side FET. See the layout…
Part Number: LM5143 Tool/software: Hi,
A my account is used 2 pcs of LM5143 to implement Single -output multiphase operation (similar with Figure 9-10). both master and slave LM5143 can't enter DEM mode even without load connection.
customer wants…
Part Number: LM5143 Other Parts Discussed in Thread: LM25143 Tool/software: Good afternoon, I use LM5143 to carry out a 24V to 12V dual-phase BUCK circuit, but it can't work, and the phenomenon is strange, the output is only 0.5V, and the SW has no waveform…
Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143 Tool/software: Hi,TI experters
when LM5143 use to Two-Phase, Single-Output Buck Regulator 3.3V,how test gain margin and phase margin.
I place to injection point is 1 ,or 2 or 1&2 .I am…
The crossover frequency should be set at 10-12% of Fsw.
The discontinuity at 36kHz is likely due to an inadequately damped input filter, which is worst case at full load.

Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143 Tool/software: From Datasheet i can understand that using FB1 setpoint i can Design for adjustable output voltages, but i have a Query on Input voltage set point,my question are as follows…
Part Number: LM5143 Other Parts Discussed in Thread: LM5141 , LM5190-Q1 , LM5190 Tool/software: Hello,
I am trying to make a MPPT charge controller with the LM5143, i would like to convert the LM5143 in a CV/CC converter.
The software would change the…
Part Number: LM5143 Tool/software: hi sir
I want to design a power stage , spec as below, Normal, 24V input, -5V output in 60A.
could you help to check the schematic &layout
thanks

Part Number: LM5143 Tool/software: Hi Team,
Greetings of the day!!
Our Requirements are listed below:
Input voltage is Vi = 36V.
Output voltage is Vo = 0.6 to 24V.
So we design to draft the Schematic of LM5143 in Single-Output Multiphase Operation.

Part Number: LM5143 Tool/software: Hi,
I found LM5143 have dual phase function but don't know it can support to this kind of high current output.
And there seems have some different application
(1) LM5143 * 1 dual phase.
(2) LM5143 *2 dual phas…
