Hi Team, I would like to seek your insight into this matter.
I used 20uF input cap and 4.7uF output and also tried 10uH inductor, it still does not provide 3.3v at the output. Here I would like to clarify that on No load, I can obtain 3.3v at the output, however, when I connect to the microcontroller circuit, the voltage drops to 2.5 V. I test the current requirement of the microcontroller circuit, it reaches a maximum of 75 mA. However, there is always voltage drop at the tps61097 output, I tried it on different boards, same issue. Is it possible that the chip goes into some overload lockout ?
Thank you very much.
