TPS65150: TPS65150 design questions

Hi Team

We used TPS65150, but meet some issues on the design:

Input requirement, 3.3V

Target VGH = 18V, VGL=-14V, VS=10V, the design is as below.

It seems that the device enter into OVP, only VS=3V, could you help check below design Rfb value?

Hi Thomas,

Did you use the EVM or your own designed board? The schematic you attached seems the EVM.

Hi Patrick，

Yes, we take EVM design as reference and red line is modified value in customer board.

Thanks

Hi Thomas,

OK, please let customer capture the waveforms of VS, CPI and DRVP when power on the IC. This will help to find out which power rail is having issue.
