ELECTRICAL CHARACTERISTICS (continued)
Note 3: The equation for the target voltage V
Note 4: On-time and minimum off-time specifications are measured from 50% to 50% at the DH_ pin, with LX_ forced to 0V, BST_
Note 5: Specifications to -40°C and +105°C are guaranteed by design, not production tested.
