Typical Operating Characteristics
(Circuit of Figure 1, T
A
= +25
°
C, unless otherwise noted.)
Note 5:
The step-up current limit in startup refers to the LXSU switch current limit, not an output current limit.
Note 6:
The idle mode current threshold is the transition point between fixed-frequency PWM operation and idle mode operation
(where switching rate varies with load). The specification is given in terms of inductor current. In terms of output current, the
idle mode transition varies with input-output voltage ratio and inductor value. For the step-up, the transition output current is
approximately 1/3 the inductor current when stepping from 2V to 3.3V. For the step-down, the transition current in terms of
output current is approximately 3/4 the inductor current when stepping down from 3.3V to 1.8V.
Note 7:
Operation in dropout (100% duty cycle) can only be maintained for 100,000 OSC cycles before the output is considered
faulted, triggering global shutdown.
Note 8:
Specifications to -40
°
C are guaranteed by design, not production tested.
