Non−Latched Enable Input
the BO terminal voltage grows above 2 V threshold. The
enable comparator features 100 mV hysteresis so the BO
terminal has to go down below 1.9 V to recover IC operation.
The non−latched input stops output drivers immediately

This input offers other features to the NCP1392 like
dimming function for lamp ballasts (Figure 30) or skip
mode capability for resonant converters (Figures 31
and 33).
