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.

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

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.

Guaranteed by design.

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