Typical values are at T
6
Note 2: On-time specifications are measured from 50% to 50% at the DH pin, with LX forced to 0, BST forced to 5V, and a 500pF
Note 3: Production testing limitations due to package handling require relaxed maximum on-resistance specifications for the thin
Note 4: Specifications to -40°C are guaranteed by design, not production tested.
