Part Number: TPS65150 Tool/software: 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…
Part Number: TPS65150 We are using TPS65150 with VIN = 3.3 V, generating AVDD ≈ 8.2 V, VGH ≈ 12.5 V, and VGL ≈ −13 V.
Since one negative charge-pump stage can only regulate down to about −VSUP + VDROP, a second VGL stage is implemented as per datasheet…

Hi expert,
1) How to handle the unused pin on TPS65150 VCOM and VIN?
2) We disabled the FDLY and added the power down seq as above, because of there is power down seq circuit, there…
Part Number: TPS65150-Q1 To meet the power-down timing requirements of DMD, we want the three power supplies (SUP) 10V, (VGH) 18V, and (VGL) -14V to power down quickly, so we added a discharge circuit.
If a 1.2A instantaneous pulse current lasting 100µs…
Part Number: TPS65150 Tool/software: Some product carry an CTRL or FLK input for LCD gate shaping signal. Are there any examples or actual controllers that have such output or does this signal come from the LCD itself ?
Part Number: TPS65150-Q1 Dear TI experts,
My customer made thdir PCB using TPS65150-Q1. But is does not work properly.
Could you review the schematic first?
Customer applied 4V to Vin. And they measured 2 pins below.
LCD_AVDD : They set…
Part Number: TPS65150 Tool/software: Dear Team,
We are using the TPS65150 LCD Bias IC in our design. Attached is the screenshot of the schematic as well.
We provide 3.3V as input to the IC, and we were able to get the required AVDD voltage of 8.2V…
