Powerboost 500C TPS61090 problems

by neo26 on Tue Aug 25, 2020 11:03 am

I have been trying to simulate the 500C 5V system using basically the same setup. However, I am using the 61092 chip that has the set 5V instead of the variable you use. I keep smoking it. Did you have problems with this chip? How do you ground the pad as the board diagram is not easy to read? I have ordered a breakout board with correct padding and ran that to ground and I get the same. Some run for a week, others smoke after 30 seconds to 5 min. Especially when I put a power supply to it instead of the battery to test the LBO LED. WHat am I do wrong? Did you guys have trouble with this finicky chip?
