Part Number: TPS54140A Tool/software: WEBENCH® Design Tools Hi Champs,
when exporting in Webench the simulation of a design to TINA it does only export the startup simulation.
Is it also possible to export the steady state, load transient....simulations…
Hello,
Thank you for sharing your schematic.
As Robert said, this may be okay. You will want to verify the stability of this design for your range with loop response measurements. You can also use the circuit calculator tool in the product folder…
Part Number: TPS54140A Hello team,
I have a quick question regarding TPS54140ADGQR.
We can see two types of packaging information in p.51 and p.53 of its datasheet. Theremal pad area is described as below.
p.51: 1.57×1.88mm p.53: 1.83×1.89mm
Which…
Part Number: TPS54140A Hello,
Now I have an question about GND layout for TPS54140A.
The GND patterns on top layer of the TPS54140EVM are divided such as attached image.
On the other hand, when I refer to the 'Figure 65' of the datasheet I find…
If the only thing on VIN is few capacitors then the VIN caps will charge up to ~4.3V and the body diode will stop conducting because there's no more load.
I'm assuming the isolation transformer on VIN also has a diode to rectify the output of the transformer…
Hi,
I got the question from my customer.
There is some output ripple waveforms on the datasheet, and they look like the band pass filtered as following.
Could you tell me what filter is used?
Best Regards,
Kuramochi
Other Parts Discussed in Thread: TPS54140A I need application help with determining the compensation network for a TPS54140A SMPS.
My input voltage range is 8-18V (nominal input is 12V). My output is 5.0V @1.0A. My desired switching frequency Fsw, shift…
Other Parts Discussed in Thread: TPS54140A , TPS54140 Hello, team
TPS54140A's thermal information is drawed below in datasheet.
(DGQ PKG)
θja = 62.5 , θjctop = 83
(DRC PKG)
θja = 40 , θjctop = 65
They are shown θja > θjctop.
Is it correct…
Hi Anthony,
While they're updating the datasheet for the TPS54140A, the section on "Adjusting the Output Voltage" and "Enable and Adjusting Undervoltage Lockout" should be cleaned up so that both sections don't use the same resistor designators. There…
Other Parts Discussed in Thread: TPS54561 , TPS54140A Hi Team
Please explain in detail the design considerations that should be taken into consideration when connecting in sequence a TPS54561 and TPS54140A, by coupling the PWRGD pin in TPS54561 to the…
