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 if there…
Part Number: LM5119 Other Parts Discussed in Thread: PMP , TINA-TI Hi team,
I have downloaded simulation model for LM5119 and try to run simulation in Tina ti. But i am unable to run it. It shows error in simulation at some nodes which are not visible…
Part Number: LM5143 Other Parts Discussed in Thread: PMP31210 , LM5119 , LM5148 , LM5146 , LM5145 Hi, do you know why the LM5143 (Synch Buck controller) was used for this Synch Buck spec (PMP31210 ref design) of 20-58vin and 13.5Vout and 50A out?... PMP31210…
Part Number: LM5119 Other Parts Discussed in Thread: UCC29002 , Hi
I have a customer interested in paralleling up to 8 power stages controlled by 4 LM5119 controllers with equal current sharing between the power stages. The option of using the UCC29002…
Part Number: LM5119 Hello. I have an inquiry about using the LM5119 from a customer. In the datasheet, if you look at the tss calculation formula of the Soft Start Capacitor, the Css value of 0.047uF is applied.
1. I am trying to apply a Css value of 0…
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 Qian,
Are there any known issues with DCM when using the LM5119 in interleaved mode (single output)?
I am seeing multiple LM5119 failures at > 40V input voltage / no load on the output with DCM, but in CCM this problem seems to…
