Note 2: Output current specified with circuit of Figure 2 and CoilCraft D01608-334 inductor for test purposes only. More (or less)
output current can be supplied with other coil types depending on inductance value and coil resistance. See Typical Operating
Characteristics for other coil types. Output voltage and output current are guaranteed over this V IN operating range once the
device has started up. Actual V IN start-up voltage depends on load current.
Note 3: Output voltage specifications over temperature are guaranteed by design to limits that are 6 sigma from either side of the mean.
Note 4: Current measured into OUT. V OUT is forced to 3.47V to maintain LX off when measuring device current.
