Part Number: TPS65160 We are using TPS65160 in our project for TFT display.We are not getting VGL(-5V) as per our design what may be the issue?Vcom is also getting wrong (5V instead of 3.3V)
Please guide.We are using recommended circuit .
Part Number: TPS65160 Hi guys,
I'm working on a LCD-TFT-like project. I found out this TPS65160 chip is dedicated made for LCD-panel as a PMIC with a controllable power-on sequencing, which is also very import for my board as well. I need VS and V_logic…
Part Number: TPS65160
I’m trying to use the TPS65160 to provide biasing voltages for an LCD panel. The TPS65160 part provides 4 output voltages Vs, Vgh, Vgl, and Vlogic. In my application I do not need Vlogic. But startup sequencing and the Enable pins…
HelloYuan,
I would suspect some electrical over stress like a high voltage on the SW pin to have caused short to GND and the likely reason is Q1 failure due to this over stress. If you would like, you can initiate a return to TI quality team for failure…
Other Parts Discussed in Thread: TPS65160 Dear expert:
it looks on TPS65150 data sheet, the VS is always before than VGL, any solution can solve below problem? 5V power supply needed, so TPS65160 can't use. thanks.
Robin
Other Parts Discussed in Thread: TPS65160 , TPS65150 Hi experts,
In our product, we use TPS65160 to get Vs,VGH,VGL,VCOM. The power input of TP65160 is a 3.6V DC power supply.
The 3.6V power supply is controlled by a power switch.
In our application…

Hi Expert
I tried to understand the CFF calulate and I have some question need your help
the equation shows below in datasheet : my Cout : 66uF, VREF=1V, Vout=3.3V, RFBT=100K , chip freq=2MHz , Loading current from 150mA…

Please use this power point for your reference. Basically, you need to take the bode plot and determined where the place the zero in the transfer loop…
loop estimate using transient response.pdf Hello,
Yes it is possible to correlate transient response to phase/gain plots.
This attached app note describes how to estimate phase/gain from looking at output transient response. See Figure 5. So it is…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
