8 / 40 page  Limits apply over TJ = –40°C to 125°C, VIN = 24 V, VOUT = 3.3 V, VLDOIN = 5 V, FSW = 800 kHz (unless otherwise noted). Minimum and maximum limits are specified through production test or by design. Typical values represent the most likely parametric norm and are provided for reference only.

Not production tested. (2) Production tested with VIN = 3 V. (3) This is the current used by the device while not switching, open loop, with FB pulled to +5% of nominal. It does not represent the total input current to the system while regulating. 7.6 System Characteristics The following specifications apply only to the typical applications circuit, with nominal component values. Specifications in the typical (TYP) column apply to TJ = 25°C only. These specifications are not ensured by production testing.
