Data Sheet
ADP1612/ADP1613
SPECIFICATIONS
VIN = 3.6 V, unless otherwise noted. Minimum and maximum values are guaranteed for TJ = −40°C to +125°C. Typical values specified
are at TJ = 25°C. All limits at temperature extremes are guaranteed by correlation and characterization using standard statistical quality
control (SQC), unless otherwise noted.

1 This parameter specifies the average current while switching internally and with SW (Pin 5) floating.
2 Current limit is a function of duty cycle. See the Typical Performance Characteristics section for typical values over operating ranges.
