ADP1614
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 when the device switches internally with the SW pins (Pin 6 and Pin 7) floating.
2 Current limit is a function of duty cycle. For the adjustable current limit versions, it is also a function of the resistor on the CLRES pin. See Figure 9 through Figure 12.
3 Guaranteed by design.
4 The CLRES pin cannot be controlled with a current source. An equivalent resistance should be used.
