I can't let TPS61030 work at 2V input, 5V output when output load is 10 Ohm(>0.5A) on my PCB. I decided to run simulation first and download the TINA circuit SLVM099. I just change the load resistor(RLOAD) from 20 to 10. The result is the same as I test on real PCB. The output is only 3.2V and the TPS61030 is not switching. The simulation file and waveform are as attached. Can any body help me find the problem?
Thank you
