Hello
I've built a circuit around an LTC3111 Buck-Boost Converter chip following Linear's design. I keep burning them out (Vcc and GND become internally shorted) in this configuration and I am not knowledgeable enough to correct my error. My guess is that the voltage divider, the only difference between my implementation and LT's design, is the problem. Can anyone offer insight into this problem?
Thanks
