  • TPS65150: TPS65150 isn't starting / internal reference isn't coming up

    Part Number: TPS65150 Hi TI Team, I am using the TPS65150RGER to generate the required bias voltages for an LCD application. The input supply to the IC is 5 V . However, the IC is not generating the expected output voltages. The main boost output…

  • 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: Vgl and Vgh out put is not coming

    Part Number: TPS65150 I want to design Vgl = -9v and Vgh = 18v. my Vs Output is 10V, i changed the resistor combination accordingly but the output is not coming as expected. let me know how to trouble shoot step by step.

  • 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: No boost output

    Part Number: TPS65150 I've seen some other posts on the forum with similar questions but no responses. I'm attempting to implement TPS65150 in the HTSSOP package to generate the rails as shown on the schematic below: AVDD = 9.6V VGH = 18.0V VGL…
