Boost Converter Characteristics
Note:
1. Characteristics obtained with the setup described in section “Boost Converter” on page 168.
2. Minimum shutdown voltage is not guaranteed. At very low battery voltages the logic may cease to operate before issuing a
stop signal. Application firmware can use the ADC to monitor battery voltage at regular intervals and issue a firmware stop
when required.
