TPS61170: About Device Operation After Applying Static Electricity

Part Number: TPS61170


The customer tested the application with a static electricity test. When static electricity was applied to the LCD attached to the application instead of the TPS61170, the waveform was similar to Fig. 1 in the attached document.
Could you comment on the following questions?

1. After supplying static electricity, Vin decreased and Vout=Vin (Fig. 2). I think this behavior is due to UVLO, is that correct?

2. In Figure 3, when Vout=Vin, CTRL=Low was entered, and then Vout became the desired voltage (24 V). Could you tell me why Vout=24 V even though CTRL= Low?
