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 to change…
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…
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: 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? …
