6.5 Electrical Characteristics (continued)

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.
