We are observing very high-power consumption (600-700mA) and buck boost IC being damaged when supplying through Lithium battery packs 1S (~3.7V) but not with AA battery packs 3S (same voltage)
We are writing to request a design review and discussion to understand the source of these issues. We have followed typical application circuitry and layout considerations. Here is the schematics attached for reference: Power Card 2.2.2
Please suggest the earliest suitable date and time. We operate in India (IST), so we would appreciate a time slot that is not too inconvenient for us.
Thanks
Abhi
