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.
