Hi Jasper,
My customer have meet TPS61070 damaged issue, they found SW pin short to GND, fail rate about 3%, total 50/1400.
Schematic as below, customer said they have meet this issue before, but they change the inductor from 4.7uH to 3.3uH, seems solve this issue, but now used 3.3uH but still found damaged in this project.
Do you have any idea about this? Human finger is possible let the IC damaged(I saw the FB pin sensitive issue on E2E, if finger touch caused Vout raise up)? or have you meet this SW pin damage issue before?
Or any information need I provide please let me know.
thanks!
Jeff
