Maximum and minimum limits over temperature are guaranteed by design and characterization. Note 2: On-time and off-time specifications are measured from 50% point at the DH pin with LX = GND, VBST = 5V, and a 250pF capacitor connected from DH to LX. Actual in-circuit times might differ due to MOSFET switching speeds. |
