  • TPS65150: Change voltage setting on TPS65150

    Part Number: TPS65150 Dear all, I am already using the TPS65150 on a device that drive a TFT, and I generate the following voltages correctly: VS (Avdd) = 8,2V, VGH=22Vdc, VGL=-7Vdc, Vcom=3Vdc Now, to generate VGH I have a double stage. The new…

  • TPS65150: TPS65150 design questions

    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…

  • TPS65150: TPS65150 failure during power on off at high temperature

    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…

  • TPS65150-Q1: TPS65150 unused pin and current questions

    Part Number: TPS65150-Q1 Other Parts Discussed in Thread: TPS65150 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…

  • TPS65150-Q1: The effect of pulse current on the TPS65150 chip

    TI Thinks Resolved
    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…

  • TPS65150: TPS65150 gate shaping control

    Resolved
    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 ?

  • TPS65150-Q1: Please review the schematic of TPS65150-Q1

    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…

  • TPS65150: TPS65150 VGH & VGL voltages issue

    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…

  • TPS65150: Not getting Vs boost output

    Part Number: TPS65150 Hello, We are using TPS65150 for LCD driver but we are not getting Vs boost output. We are getting 5V at Vs same as Vin. Find attached Schematic FET3562-C_V1.0_31122025.pdf

  • TPS65150: Design Review of Schematics and PCB Layout of LCD Bias Circuitry

    Part Number: TPS65150 Hi Team, We are using a 10.1" Display with the following voltage requirements - As per the display driver datasheet , the current requirements for each of these voltages are - AVDD = 9.6V @ 10mA VGH = 18V @ 200uA VGL = -6V @…
