Tool/software:
I am operating TPS63070 in PFM mode where input can be 4V to 6V while output is set to 5.8V. When started at no load, I observed the output as 5.8V & then goes to 9V. This happened on two units momentarily. After power cycle, the output got correctly to 5.8V. I do not have a Waveform captured for this inconsistent issue. Can you comment if the part stable at no load? Can you help to suggest what could be wrong here? Only thing I can think of is dry solder of the Top feedback resistor. As an additional information, my design has VSEL pin as connected to GND.
