Hi team,
Customer has some questions, here is the details
I am driving the LED using LP5030(LED DRIVER), but there is a measurement waveform for the output current waveform in databook, but there is no measurement waveform for the output voltage waveform, so I am inquiring. I measured the output voltage waveform of OUTX as shown below. It does not drop to 0V under PWM control. Is there any problem? Why doesn't it drop to 0V?
Output OUTX terminal voltage waveform when CH1(yellow)is LED operating
Could you help?
Thanks & Best regards,
Vivian
