Part Number: TPS54140A Hi team,
We use this device for Split-rail power supply(Vin=15V, Vout=±12.5V) referenced slva369a. And we plan to add R-C snubber to parallel Voneg side diode to dump out the ringing.
There is two questions.
1. Is it okay…
Part Number: TPS54140A Dear TI Team
When I carried out WEBENCH under the following conditions, the following circuit came out. Vin = 4.75-32V Vout = 3.75V Iout = 1.5A
At this time, if you check the voltage applied to the EN terminal from the voltage dividing…

Hi,
My customer requests the thermal resistance on the four-layers board condition.
Does anyone have it?

Part Number: TPS54140A Other Parts Discussed in Thread: TPS54140 I download TPS54140 Unencrypted PSpice Transient Model in the web and simulated in LTspice.
After I analyze the circuit, there are some error.
I set the switching frequency to 220kHz.
But,…
Part Number: TPS54140A Tool/software: WEBENCH® Design Tools Hi team,
I am using webench to design power from below specs,
Vin=10.8-28V, Vo=5V/1A, the feedback resistor is 56.2k//10k. For internal voltage reference is 0.8V, I think the resistor should…
Part Number: TPS54140A Other Parts Discussed in Thread: TPS54140EVM-429 , , TPS54140 Hi
Is it enough to evaluate TPS54140A using TPS54140EVM-429?
Because there is no EVM for TPS54140A.
BestRegards
> 1) TPS54140 and TPS54140A should have samilar output ripple perfromance . There is just Enable threshold improvement in the A version . I think thers's a trivial difference of behavior in very small load. > you can use lower inductance value and…
Part Number: TPS54140A Hello Can someone tell me which current I can use for formula 8 and 9. Is the inductor current IL the same as the wanted current out? If I would use formula 12 To calculate the current I need the frequency result from formula 8 and…
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 to…
