Part Number: TPS54620 Tool/software: Hello,
Question for below:
1) In the error amplifer, how to read the phase margin? I suppose it should go to -180, but it's not.
2) For the control loop, what's specfic in schematic? I suppose it should be the…
Part Number: TPS54620 I have been trying to track and debug an extremely odd system failure on a PCIe add in card and after a long frustrating incremental process of debug have determined that at least one of the points of failure is in the power system…
Part Number: TPS54620 Hi,
Is there a document explaining the fault mode of TPS54620? such as the impact of short circuits or open circuits on the output of each pin.
Thanks!
Part Number: TPS54620 Tool/software: Hello,
We are using TPS54620 in one of our project for avionic. We need pass conducted and radiated EMI according standard RTCA-DO160 Cat M.
Unfortunately we did not pass conductive limits at frequencies 749kHz…
Part Number: TPS54620 I am trying to analyze an existing dc-dc converter to redesign it. Webench keeps changing the component values back. Is there anyway to analyze a custom design on Webench?
Part Number: TPS54620 Hi TI experts,
In our design, there is an uncontrollable high pulse (3.3V) applied to EN pin before normal power up sequence starts.
The pulse width is about ~10ns. Is there any deglitch filter inside TPS54620 EN pin which can…

Tool/software:
I tried to use tps54620 to power the FPGA,but the 1.8V output is only about 0.8V, and the COMP pin is a sawtooth wave?I used to use it in other borad,the Vin is 12V,it works well。This time I change thne Vin to…
Part Number: TPS54620 Hi team,
My customer is using our TPS54620.
Could you please kindly help check below two questions:
1. How to choose TPS54620 EN pin Vstart and Vstop ?
2.Vstart and Vstop means which pin's voltage? ( Ven or Vin )
Thanks…
Part Number: TPS54620 Tool/software: Hi Experts ,
What is the difference between TPS54620RHLR & TPS54620RGYR ?
I have checked the technical specs of both there is no differences and have same package code. Can we use HLR for GYR part ?
Technically…
Part Number: TPS54620 Other Parts Discussed in Thread: TPS53355 Tool/software: 使用前级5.2V作为输入,tps53355输出1.0V,tps54620输出1.8V,3.3V,1.5V,1.0V有输出, 1.8V输出只有0.8V左右,COMP引脚是锯齿波,请问是什么原因导致的?
