ADVANCE INFORMATION for pre-production products; subject to change without notice.
Foldback protection modes are entered when the duty cycle exceeds the minimum on and off times of the part. At very high duty cycles, where the minimum off-time is not satisfied, the frequency folds back to allow more time for the peak current command to be reached. The maximum on-time is 8 µs (typical), which limits the maximum duty cycle in dropout to 98% (typical).
