Note 1: This is the time from an output overcurrent or short-circuit condition until the output goes into regulated current limit.
Note 2: OUT voltage above which the output current limit is at its full value.
Note 3: See the Overcurrent Protection section.
Note 4: This is the time the part stays in current-limit mode during overload condition. After t
OC
elapses (or when the junction tem-
perature hits +150癈) the part shuts down.
Note 5: See Typical Operating Characteristics.
Note 6: This is the delay from I
OUT
falling below the zero-current threshold until ZC goes low. A ZC condition shuts down and latches
off the IC.
Note 7: See the Fault Management section.
