Hi,
I have designed a TPS63802DLAR Boost converter.
Following image details the Input/Output parameters designed for.
Have followed the same Schematic.
This is the PCB layout for the Boost Converter
Application - Powering a 5V Lock + Buzzer combination with a 3.7V Li Ion Battery input
The TPS63802DLAR constantly keeps burning when connecting input power out even without connecting a load. I'm assuming the IC has burntout since inital tests after board assembly used to yield 5V output however after a while, the IC tends to heat up and stops providing 5V output.
Is there anything I need to rectify in my PCB layout or schematic that could help solve this issue.
Looking forward to your assistance.
Thanks a Lot!
