Note 1:
Specifications to -40°C are guaranteed by design, not production tested.
Note 2:
When the inductor is in continuous conduction, the output voltage has a DC regulation level higher than the error-compara-
tor threshold by 50% of the ripple. In discontinuous conduction, the output voltage has a DC regulation level higher than the
trip level by approximately 1.5% due to slope compensation.
Note 3:
On-time and off-time specifications are measured from 50% point to 50% point at the DH pin with LX = GND, V
BST
= 5V,
and a 250pF capacitor connected from DH to LX. Actual in-circuit times may differ due to MOSFET switching speeds.
