NOTE 1:
The reverse battery current is measured from the Typical Operating Circuit's input terminal to GND
when the battery is connected backward. A reverse current of 220mA will not exceed package dissipation limits
but, if left for an extended time (more than 10 minutes), may degrade performance.
NOTE 2:
Start-up guaranteed by correlation to measurements of device parameters (i.e. switch on-resistance,
on-times, and output voltage trip points.
NOTE 3:
tOFF = Ratio x
. This guarantees discontinous condition.
NOTE 4:
Specifications to -40oC are guaranteed by design, not production tested.
