Hi experts,
In our product, we use TPS65160 to get Vs,VGH,VGL,VCOM. The power input of TP65160 is a 3.6V DC power supply.
The 3.6V power supply is controlled by a power switch.
In our application, the 3.6V power supply is sometimes disabled and then enabled.
Sometimes, after the 3.6v power supply is on, the Vs voltage of TPS65150 is equal to that of input power supply.
The schematics we use are same as that on datasheet of TPS65150.
Why does TPS65150 not work?
