Hi team
Here we have encountered a issue that when LP87524 outputs abnormally. When the EN is high (green waveform), the LP87524Q1 output is 1.8V but when EN from high goes low, the LP87524Q1 output is abnormal and the voltage value is around 1V, here is the waveform:
Green one is EN signal and the yellow one is LP87524Q1 output, could you please help to analyze it and what potential factors will cause this issue? Here we also dump the LP87524Q1 register, thank you.
