we are using the LT8611 for charging a 12V lead acid battery.
When the 24V input voltage is removed the LT8611 will be destroyed.
We added a diode like the recommendation from the LT8611 datasheet (page 18, figure 5) but this didn´t prevent the fault of the LT8611 when the input voltage is absent.
The schematic is attached below.
Any help is greatly appreciated,
correct spelling of Subject "damaged"
