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: Specifications to -40oC are guaranteed by design, not production tested. NOTE 3: Inductor Peak Current where . IPEAK = 1400 R LIM R E T E M A R A P. N I M. P Y T.
