Note 1: Specifications to -40°C are guaranteed by design, and not production tested.
Note 2: When the inductor is in continuous conduction, the output voltage will have a DC regulation higher than the trip level by
50% of the ripple. In discontinuous conduction ( SKIP = AGND, light load) the output voltage will have DC regulation
higher than the trip level by approximately 1.5% due to slope compensation.
Note 3: On-time and off-time specifications are measured from the 50% point at the DH pin with LX = PGND, V BST = 5V. Actual
in-circuit times may differ due to MOSFET switching speeds.
