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 for…
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
HI Steve
Sorry for delayed response, We have fixed this issue, Changes will be available on ti.com by next WEBENCH release(Tentatively by end of this week)
Attaching the WEBENCH design report for your reference.

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 from WEBENCH…
Where ever the TPS54JB20 can work, the TPS548B28 will work. Just change the feedback resistors.
The TPS54JB20 and TPS548B28 are same base silicon but with different otp trims for the fault response and voltage reference.
The issue with webench as been…

Part Number: TPS543C20 Other Parts Discussed in Thread: TPS543B20 , , Tool/software: Hello
I designed a DC/DC for 12V to 1.2V 20A load. The problem is that when I just use a 0.5ohm load which is around 2A, it is fine, but when I increase the load to 0…
Hi,
I reviewed the TPS543C20A schematic and there is only one issue I notice: With your current configuration the expected current limit is 42.5A, with 10% tolerance plus resistor tolerance, the margin might not be large enough to support 39A full load…
Part Number: TPS546C20A Other Parts Discussed in Thread: TPS546C23 , I am facing two issues with TPS546C20A on a single phase design.
Input: 12V
Output: 0.845V 30A
Issue 1: On the measured loop gain, at the low frequency region (1kHz to 4kHz, see Case…
Hi Jospeh,
Thanks for your inputs.
I have updated the power calculator and selected suitable Feedback and compensation network. Please review the schematics and power calculator bode plots and provide if any review comments. I would like to release the…
