Timing Diagrams
During normal operation, if the OV pin exceeds OV HIGH, as
shown at time point 1 in the above diagram, the TIMER
status is unaffected. The GATE and PWRGD ( for LM5068-1
& -2) pins are pulled low and the load is disconnected. At

time point 2, OV recovers and drops below the OV LOW
threshold, the GATE start-up cycle begins. If the load capaci-
tor is completely depleted during OV conditions, a full
start-up cycle is initiated.
