Part Number: TPS54341 Hi Team,
In the datasheet, to get the 5V nominal voltage at the output, 5.2V is required at the input and the Iout is 0.43A. Similarly, for 3.3Vout, 3A-Iout- What is the min input voltage required?
I hope you can clarify. …

Hi Team,
Our customer would like to clarify the operating temperature range of TPS54341 and LMR51440. The operating temperature range stated in the product page of TPS54341 is -40C to…
Part Number: TPS54341 Other Parts Discussed in Thread: TPS54360 Hello,
I am using two TPS54341 components in my design, one for 24V-to-12V regulation and one for 24V-to-5V regulation. I have them configured for ratiometric startup and have simulated…
Part Number: TPS54341 Dear Support,
There is a confusion on the PWRGD of the TPS54341DPR design. Kindly know the technical usage of PWRGD signal in the particular design.
TI designs recommend to keep reference 5V on the PWRGD Pin with 1K pull up.…
Part Number: TPS54341 Hello Guys,
Good day.
During testing of our customers circuit board, a TPS54341 5V regulator could be unpowered at the input and experience 3.3 VDC applied to its output. Will this damage the TPS54341 circuit?
Note that this…

I already have a case open CS0175983 I'm trying to understand why the SS does not appear to be working correctly. Conditions: VIN = 24V (ramps from 0-24V in 9ms) VOUT = 15V Css = 22nf (looking for a 10ms ramp from 0 to +15V in…
Part Number: TPS54341 Hi E2E,
Good day!
May I know how to get the value of the average soft-start current (Issavg) discussed on section 8.2.2.6 Slow-Start Capacitor page 33 of the TPS54341 datasheet? Is there an equation on how to get it?
Looking…
I am using 100uF (3x33uF Tantalum polymer T521 Kemet) capacitors in the Buck converter output currently. I will try with higher value capacitance and observe the operation. Thanks.
Hello,
When the datasheet mentions that "The capacitor must also have a ripple current rating greater than the maximum input current ripple of the TPS54341 device". This means the current rating of the input capacitor must be able to handle the maximum…
Igal,
You can definitely try different values of Rboot. And a snubber is a good idea. This Application Report has lots of great info for selecting and optimizing boot resistors and snubbers.
If you do another layout spin, you could also reduce the…
