Dear support team
My customer found the level of TWL1200-Q1 output falls (see attached file)
(1)Could you advice about cause of this and solution?
(2) I guess parasitic capacitance of output side is influence. but it is written in datasheet that capacitance is less than 75pF
How much is the values of recomendation of this board?
■Finding
・When it is short between SD connector and FPC (reduce parasitic capacitance) on TFT board, wave pattern is improved.(See waveform 2)
・When output is open waveform is improved too.
