Our settings:

VCCSW - 5V from 2.5A regulator

Mode - 7Vrms

Boost output - 12V (Internal boost mode)

Issues:

1. Series to inductor it is drawing more current - 300mA, but boost output voltage - 12.5V

2. IC is heating up and it is keep on increasing - 100+ deg C ( check via thermal camera)

Images are attached for reference. Please help on these issues.
