Part Number: TPS65150 Hi,
The old TPS65150 datasheet do mention tied FDLY to VIN for disabling fault shutdown function, but the latest datasheet is not talking about this.
My customer want to know whether they could follow old datasheet (see below link…
Part Number: TPS65150 Hi,
My customer will use new panel from Innolux, but it looks VGL cannot meet the requirement if AVDD is 8.2V.
Could you please provide suggestion for this new panel requirement?
AVDD= 8.2V
VGH= 12.5V
VGL= -13V
Thanks and Best regards…
Part Number: TPS65150 Hi,
I would like to know for below I(DLY1)/I(DLY2)R(FDLY) minimum and maximum condition is based on TA = –40°C or 85°C.
As I know in normal Silicon characteristic, 3uA/250kohm minimum spec should be in low temperature –40…
Part Number: TPS65150 Hi team,
When using TPS65150 as below SCH, the DRVP can't work normally. For the test diagram, left one is abnormal and right one is normal. I asked customer to change a larger Cfly, but it still doesn't work. The negative charge…
Part Number: TPS65150 Hi,
We are using TPS65150 in our design. As per the datasheet section 7.3.5, VCOM will start once Vcpi reaches its final value. We want sequencing as VCOM starts once VGH is reached its final value.
With default option, VCOM is rising…
Part Number: TPS65150 Other Parts Discussed in Thread: TPS65131 Hi,
We are using TPS65150 in our board. Attached the schematics of our design.
The set values are below.
Input : 5V AVDD: 8.2V VGH : 22V VGL :-7
Currently we are facing issue with output voltage…

We are trying to find a device of LCD bias which can support 11V boost output, GCH, VHL. TPS65150 can support, but we do not need the VCOM buffer to save cost. …
Part Number: TPS65150 Hi Expert,
Could you please let me know about the reason of ramp up VCOM and VGH during AVDD rampap timing as below?
Ch1 (yelow): VCOM
Ch2 (Blue) : AVDD
Ch3 (Pink) : VGL
Ch4 (Green) : VGH
Is it no problem?
Thanks
