Part Number: LM5119 Other Parts Discussed in Thread: TPS54061 Hello e2e-community, I´m using an LM5119 buck controller in interleaved mode with external supply provided by TI TPS54061 to reduce power dissipation as shown in schematics below. Key parameters…
Part Number: LM5119 Hi,
my assigned customer wants to use LM5119 in this configuration:
dual phase, Vin = 18V..60V, Vout = 12V, I_load_cont = 12A, I_peak = 16A
They tested the EVM and noticed, that the current in both phases differs a lot. Measuered…

Part Number: LM5119 Other Parts Discussed in Thread: LM5117 , Vramp exceeds 1.2V and reaches 1.76V, but it works normally. As shown in the figure, CH2 is the output voltage, CH3 is Vramp, which exceeds the OCP protection point.why can it work normally…
Part Number: LM5119 Hi experts,
I would like to ask for below.
1) Efficiency comparison between DEMB enable and DEMB disable.
2) Any circuit that can only enable DEMB at light load.
3) Any recommendation to further decrease the no load loss (example…
Part Number: LM5119 Hello
We are looking for a solution to the problem that Low Side FET does not switch when operating with DCM. The output is normal, but the heat of the LOW side FET is a problem.
R and C of RAMP checked the datasheet and tried…
Part Number: LM5119 hi Team,
my customer is testing the LM5119 for LEV product
with Vin 25V Vout 12V Io ~ 25A
it seems when they use smaller Rsense it would observe ringing issue and become unstable.
the R sense is ~ 1.5mohm. we'd like to check…
Part Number: LM5119 hi Team,
customer using 2 LM5119 for 4 phase design.
we'd like to check on a synchronization problem.
The LM5119 RT is 26.4K ohm -> The operating frequency will be 190KHz.
If we used 200KHz sync frequency, the operating frequency…
