Data Sheet

ADP1614

SPECIFICATIONS

V_IN= 3.6 V, unless otherwise noted. Minimum and maximum values are guaranteed for T_J= −40°C to +125°C. Typical values specified

are at T_J= 25°C. All limits at temperature extremes are guaranteed by correlation and characterization using standard statistical quality

control (SQC), unless otherwise noted.

¹This parameter specifies the average current when the device switches internally with the SW pins (Pin 6 and Pin 7) floating.

²Current 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.

³Guaranteed by design.

⁴The CLRES pin cannot be controlled with a current source. An equivalent resistance should be used.
