Part Number: TPS61170 Tool/software: Using the unchanged TPS61170EVM-280 changing the FB voltage using PWM on the ctrl pin does not seem to work
PWM freq : 6 kHz, DC : 90%, 5Vpp, offset 2,5V.
Input voltage 10V.
expected FB voltage : 1.229*90% = 1.106…
Part Number: TPS61170EVM-280 Other Parts Discussed in Thread: TPS61170EVM-316 , TPS61170 , TPS61161 Hi Team,
Would you advise how to install the GUI which is TPS61170EVM-280 included in CD
Because my customer's PC doesn't have disk drive.
If you…
Part Number: TPS61170EVM-280 The TPS61170EVM-280 demo board works with minimum input voltage of 9 volt. How can I modify the circuit to accept input voltage down to 3 volt?
Hi Dice-K,
Here are just some updates, although the root cause is not clear yet.
I verified on the TPS61170EVM-280, with a separate Vin(3.3V) and Vinductor(12V). Vout is 24V.
Similar SW waveforms are observed as yours, that is, at light load the SW is…
Hello Jasper,
Please find attached waveforms on TPS61170EVM-280 original configuration Vout=24V.
When input 4.8V Vin with 100Hz 100mVpp modulated power source, we can clearly see spike noise which related to Magic Vin voltage.
Our customer is facing…
Anne,
I'm not sure about the external components of TPS61170 in your measurement, but I used TPS61170EVM-280 and just changed feedback resistor to get 12V output. the bench test result is similar to your observation. in the TPS61170EVM user guide,…
I checked the ripple across the output cap with small loop on TPS61170EVM-280.
I would like to know how much ripple(actually spike noise) across the output cap on TPS61170EVM-280 as reference.
Could you give the sample waveform on TPS61170EVM-280 for…

Hi,
Please tell me about Webench's efficiency calculation.
Why is there a difference in efficiency between the efficiency curve of TPS61170EVM-280 and Webench simulation results?

Other Parts Discussed in Thread: TPS61170EVM-280 , TPS61170 Hi,
I just got a TPS61170EVM-280, but when I try to use the TPS6116x/70x Control Software with the USB-TO-GPIO adapter box, I can't seem to adjust the output voltage of the converter.
The software…
TPS61170EVM-316 is configured as a SEPIC converter. A SEPIC converter boosts and bucks but requires more input current because the power FET needs IIN+IOUT = 24V*0.250A/12V/0.9 + 0.25A = 0.55A+0.25A = 0.8A.
The TPS61170EVM-280 is a boost only converter…
