8 / 30 page  6.5 Electrical Characteristics Limits apply over TA = –40°C to +105°C, VIN = 24 V, VOUT = 3.3 V, VLDOIN = 5 V, FSW = 800 kHz, IOUT = 3 A, (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.
