Part Number: TPS54540 Based on Webench I designed a DC/DC converter.
Input 25V. Output 12V/5A.
The prototypes showed a very high temperature on top pf TPS54540 at 4A (114ºC). Even they switched off at 5A
Then, I decided to simulate the thermal analisys…
Part Number: TPS54540 I have built a few prototype modules with the TPS45450 and they work great, however the 15V - 5V module has low frequency noise occur between approximately 0.2A and 0.35A.
As you can see the noise frequency is approximately 2…
Part Number: TPS54540 Other Parts Discussed in Thread: LM61460 , LM73605 Please refer to attached schematic section. We want to control the output voltage from a Microchip MCU through the control of an SPI pot. Although we can set the voltage as expected…
Part Number: TPS54540 Hi Sir,
Would you help check the compensator? is it appropriate for switching frequency 950KHz and 650KHz?
Vin=9V to16V, Vout=5V, Iout=3.5A, Maximum ambient temperature=85C, switching frequency= 950KHz and 650KHz
Inductor…
Part Number: TPS54540 I'm using that part (TPS54540) for 24 to 5V conversion. I'd like to have an additional 5V input connected to its output to be used where 24V is not available.
I'm wondering if that is safe or can be made safe with some modification…
Part Number: TPS54540 My customer is using TPS54540 to build 24V to 5V buck converter. The schematic is as below:
The output 5V has large overshoot at start up shown below:
The customer tried to add C623 in parallel with R242 and the overshoot could…

Hi Team,
Can you please share the excel version of the TPS54540-Q1EVM-593 BOM? My customer has the PDF from the user's guide but the excel would be helpful to price it out.
Thanks,
Antonio
Part Number: TPS54540
24V DC to 5V DC just do with reference design in datasheet , the output is ok ,but the wave form in SW pin as attached exceed the range in datasheet ：SW –0.6 45V，the max in the waveform is -2.3V.
So if this is abnormal…
Part Number: TPS54540 Other Parts Discussed in Thread: LM73605 in tps5454 0 datasheet, i found below description.
When operating with a low voltage difference from input to output, the high side MOSFET of the TPS54540 will operate at 100% duty cycle…
Part Number: TPS54540-Q1 Other Parts Discussed in Thread: TPS54540 , , TPS54540B-Q1 , LMR14050 Hi everyone
I am using a TPS54540 IC as the main buck converter in my system(to decrease 13 V to 5 V). Also, the system contains AM radio which its frequency…
