Part Number: TPS54425 Other Parts Discussed in Thread: TPS62914 , TPS62913 Hello teams
From prebious E2E support, I got following url. www.ti.com/.../slva546.pdf I found that important point is how to choice the parts inside the feedback loop.
[Question…
Part Number: TPS54425 Hello teams
Would you please check our schematic of TPS54425?
If you have any problem, please give me.
this circuite usage is bellow.
Vin 12V
Vout 5V
Iout 1.1A
Ta :85℃
we guess it does not meet phase margine…
Part Number: TPS54425 Hello,team.
Now we are considering snubber circuit. So we want to know parastic inductanc between Vin and high side FET's drain.
The details can be checked at bellow the area colored in red.
Do you have Lp2 information of…
Part Number: TPS54425 Other Parts Discussed in Thread: TPS54429 , Hello teams
But it's output ramp up only til 4V on our design. And Both Vout level is decreasing gradually until around 3.5V. As you can see in our schematic, it's behavior would happen…
Part Number: TPS54425 Tool/software: Hi Team,
I opened the FB terminal and conducted an overvoltage test on VCC_5V.
During this test, VCC_5V (blue) rose to just under 10V and then dropped to 0V, while the PG signal (yellow) remained high.
Is this…
Part Number: TPS54425 Tool/software: See post TPS54425: Regarding momentary interruption of input power
The datasheet states that UVLO is non-latching but in the previous post it was shown to latch. Will cycling the Enable pin voltage clear the UVLO…
Part Number: TPS54425 Tool/software: Hello,
My customer is using TPS54425 as shown below.
- VIN = 12V
There is a difference in input current between the development board and the mass-produced board even though the output load is the same at 5…
Part Number: TPS54425 Tool/software: Thank you for your help..
I am using it with 12V input and 5V output.
If the input power is cut off for about 150ms, the output stops. I think this is due to the UVP function, but please let me know the cause and…
Part Number: TPS54425 Tool/software: Table 1 lists 22uf to 68uf for all designs from 1V to 5V. Is there a maximum capacitance limit? Are there ESR min/max limits.
Part Number: TPS54425 Other Parts Discussed in Thread: TPS54429 , Hello teams
We want to check the behavior of TPS54429/TPS54425 with 12vin/5vout setting on TINA TI. But it's output ramp up only til 4V on our design. And Both Vout level is decreasing…
