ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1, V
specified.) (Note 1)
Note 1: Limits are 100% production tested at T
Note 2: The 0 to 0.5V range is guaranteed by design, not production tested.
Note 3: On-time and off-time specifications are measured from 50% point to 50% point at the unloaded LX node. The typical 25ns

dead time that occurs between the high-side driver falling edge (high-side MOSFET turn-off) and the low-side MOSFET turn-
on) is included in the on-time measurement. Similarly, the typical 25ns dead time that occurs between the low-side driver
falling edge (low-side MOSFET turn-off) and the high-side driver rising edge (high-side MOSFET turn-on) is included in the
off-time measurement.
