Part Number: TPS65150
Hello,
Using the TPS65150 to try and hit a V(s) of 10.383V, a V(gl) of -10.02V, and a V(gh) of ~22V. On startup the V(s) hits it's voltage, V(gl) hits its voltage, and then as V(gh) ramps up, the device seems to go into protection…
Part Number: TPS65150-Q1 H I need these rails
AVDD 11.6V @150mA max
VGH 22.0V @ 0.6mA max
VGL -9.0V @ 0.6mA max
I have a question though: VGL and VGH are generated by charge-pump networks from the ‘VSUP’ supply rail (11.6V in our case). …
Part Number: TPS65150-Q1 Hi Team,
My customer is using TPS65150-Q1 as a LCD driver on a head unit. When they are restarting the power, the LCD screen can't start. They tested the VGH and VGL are both no output. For the non-working device, the EN is normal…
Part Number: TPS65150 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 CFF correspond…
Part Number: TPS65150-Q1 Other Parts Discussed in Thread: TPS65150 HI
Now, tps65150 is used as LCD driver's high and low voltage. It needs + 18V and - 9.6V high and low voltage. In the following two problems (refer to the design below), please provide…
Part Number: TPS65150 Hello
About the soft start function, How to calculate the maximum value of switch current? I didn't see the 40% or 60% from my test result. I didn't see the third step of the soft start either.
And I increase the output capacitance…
Part Number: TPS65150 Hi team,
My customer is using our TPS65150 and see an unpredictable behavior since no load condition.
Please refer the below waveform and schematic.
We found that there is a SPIKE with a waveform of about 11.41V on VOFFSET as below…
Part Number: TPS65150-Q1 Other Parts Discussed in Thread: TPS65150 Hi Team,
The block diagram at page 1 of the datasheet in the link below shows that it can output -15v at 50mA. Please confirm if it is 50mA or 20mA only? Can it produce -10V at 50mA from…
Hi Aihua,
TPS65150 Vin specification is minimum Vin=1.8V so 2.5V is o.k. from input supply perspective. But since your input supply is not able to provide the needed load current and therefore dips,you may consider adding additional capacitance at the…
Part Number: TPS65150 Hi,
customer need a LCD power, the sepc as below.
Input is 5V, and need VCOM is adjust from VGH and VGL.
Does the TPS65150 can work here? or do you have other recommendations? thank you
