Note 1: For 5.5V < V
Note 2: Inhibits boost switching if V
Note 3: Step-up regulator switching is not enabled until BOOST is above undervoltage threshold.
Note 4: SET external resistor range is verified at DAC full scale.
Note 5: Guaranteed by design, not production tested.
Note 6: -40°C specs are guaranteed by design, not production tested.
