Part Number: TPS54140A Tool/software: We currently use the following item since many years
TPS54140ADGQ
However, during the the last period we are getting a lot of breakdowns, but we are unable to identify the cause since we are working followint the…
Part Number: TPS54140A Hi team,
Our customer using TPS54140A by Split-rail, and want to control Enable with external signal.
The use condition is Vin=15, Vout=±14V
In my understanding It is needed level shifter circuit when control enable. Do you…
Part Number: TPS54140A Hi Team,
When TPS54140ADGQR and TPS54240DGQR load is same 1.5A, Can the surrounding parts configuration of COMP pin use the same setting of TPS54140DGQR?
Part Number: TPS54140A I'm using TPS54140A for 3.3V regulation from 5V input. I have used a 10K pull down to the EN pin of this regulator to keep it off during power ON.
through software control, I will make Enable pin high (1.8V) to turn ON the regulator…
Part Number: TPS54140A Hello,
I'm having trouble reaching my desired simulation frequency on Webench.
I am trying to buck 16V to 6V @1A, however the switching frequency is capped at 1.321 MHz..
What could be limiting that switching frequency and how…
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 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 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…
