Note 5:
Current (≈ 700µA) flows into the pins during normal operation and Temperature rise calculations must be done as shown in the Applications also when an external shutdown signal on the V Information section to ensure that maximum junction temperature does C pin is greater than 0.3V. Current decreases to ≈ 200µA and flows out of the pins when external not exceed the 125°C limit. With high power dissipation, maximum shutdown holds the V ambient temperature may be less than 70°C. C pin below 0.3V. Current drops to near zero when input voltage collapses. See external Shutdown in Applications Information
Note 8:
Industrial grade device specifications are guaranteed over the section. – 40°C to 85°C temperature range.
Note 6:
A linear interpolation can be used for reference voltage
Note 9:
91% maximum duty cycle is guaranteed by design if VBAT or VX specification between 0°C and – 40°C. (see Figure 8 in Application Information) is kept between 3V and 5V.
Note 10:
VBAT = 4.2V.
