Hi ,
I design TPS65150PWP in my LCD power circuit, but I have an issue about the Vs output.
Please see the attachment of my schematic and word file of waveform.
The Vs output (net name LCD_AVDD in the schematic) cannot reach the voltage 9.6V, please also see
the waveform in the word file, when VIN applied, Vs output to 9.6 at a moment, but finally it reduce to 5V.(same as VIN)
I also remove all load of Vs. But it still output fail.
Could you help me to check what's problem?
Thanks!6661.TPS65150_schematic.pdf
