Notes
1.
The average inductor current during current limit also depends on inductance value and resistive losses in all
components in the power path. In normal applications, the average current will be limited to 2.3 A (typ.), with limits
scaled down to minimum 2.07 A and maximum 2.53 A.
V
3
is the voltage at pin 3 (UPOUT/DNIN).
If the applied high level is less than V
3
1 V, the quiescent current level of the device will increase. The maximum
increase is 300
μ
A in the event that pin 2 is at 2.0 V.
