Part Number: TPS54JB20 Hello Team,
We are simulating TPS54JB20 Buck Converter, for below values,
Vin=12V, Vout= 5V, Iout=15A, but the IC is not giving us proper results.
Vout is falling to zero volts, I have attached the photo of simulation result…
Part Number: TPS54JB20 Other Parts Discussed in Thread: TPS54JA20 Hi,
Could you please provide efficiency curve for below condition? Thanks.
Vin=12V
Vout=1.8V
fsw: 600k/800k/1Mhz
Part Number: TPS54JB20 The default webench design/ simulation (from the product folder page) at start-up attempts to run but quickly collapses to zero volts on the output - the only change was to increase the Vin_min from 4.5V to 16V.
The simulation…
Part Number: TPS54JB20 Hi All,
We have a question about how to calculate the junction temperature of TPS54JB20.
As we know the IC have multiple thermal metric parameter in the D/S.
If we want to calculate the TJ based on the power loss we got…
Part Number: TPS548B28 Other Parts Discussed in Thread: TPS54JB20 Hi,
I failed to create a design with WEBENCH for TPS548B28, the specifications are:
Vin: 6 to 9 V; Vout: 5V; Iout: 15A
It seems there are no inductor candidate for this design specifications…

Hi Brad,
Can you attach a waveform of the input supply when you are seeing this issue? Also, when you are seeing this issue how are you connecting the scope probes to the board? I would recommend using the tip and barrel method and measuring across…
