Part Number: TPS65150 Hi,
According to application diagram below, the positive charge pump schematic for C18 driving connection is tied to SW signal, but my customer does tie it to DRVP.
Based on ch6.6 switching characteristics in the datasheet, suppose…
Part Number: TPS65150 Hi Expert,
My customer have an issue of inrush current at VGH ramp up timing.
Vin = 3.3V
Vboot= 10V
VGH =21V~23V
They are using Two-Stage Positive Charge Pump. (from SW node)
At VGH ramping up, the current of 3.3V rail is around 3Amp_peak…
Part Number: TPS65150-Q1 Other Parts Discussed in Thread: TPS65150 Hi Expert,
Our customer want a pmic device recommendation, the requirement is as below:
five channels
VGH 21V
VGL -12V
VSP 6.1V
VSN -6.1V
VCOM -2~0V
And I search on TI.com and find…
Hello Jun,
I don't see any ringing in the step response of your scope plot so this looks good to me although you could have used bigger load step (datasheet graph used a 30mA-330mA load step). This converter uses input supply voltage feed forward as part…

Hi
My TPS65150 schematic is on the below.
If we don't use the VCOM buffer and derive the VCOM voltage 4V with resistor divider 165K ohm and 95.3K ohm, the 5V input supply current is normal.
If we use the VCOM buffer, the 5V…
Part Number: TPS65150 Hi,sir
1.Vin=3.3V input. Why does Vin drop to 2.5 and produce large current when C9 is out of order or fails?
2.What's the gain of Amplifier? What is the ripple requirement for VFB?
3.How does the regulating loop work?Does…
Part Number: TPS65150-Q1 Other Parts Discussed in Thread: TPS65132 Hi Team,
I search the bias IC for automotive.
Do we have the I2C function in the future?
Thanks.
Part Number: TPS65150 Hello
I'm doing TFT LCD pwr supply brd first time, hence need TI's help for review.
can you please help ? I've attched the sch page.
Also, one question, How VCOm is created ? I don't see any handle over producing VCOm…
