Can you check information regarding the below questions?
1. Thermal Shutdown condition on datasheet: Do we have rough min/max value?
2. Behavior during Thermal Shutdown: What behavior can we use to determine thermal shutdown behavior?
3. Thermal Shutdown hysteresis: Does the thermal shutdown completely shut down until the temperature has dropped by 15C? Or does TPS61170 operate for a moment on a cycle-by-cycle, like over-current protection?
