Part Number: LP8867C-Q1 Hi Team,
In LP8867C-Q1 datasheet, for the thermal information, example board layout, stencil opening, there're 2 different information.
One is P37~P38, the other one is P39~P40.
Could you clarify which one is correct?
Thanks…
Part Number: LP8867C-Q1 Hi TI Team,
We are going to use LP8867C-Q1 Low EMI Automotive LED Driver in our design. please let us know for the Driver code(file name) for this. the kernel version: 4.14.137
Part Number: LP8867C-Q1 Hi,
We are using LP8867C-Q1 in our application for TFT Backlight control.
We have a requirement to monitor the open circuit fault and log DTC. For this we are monitoring the FAULT pin and checking for the Open Circuit fault…

how to understand the decription about boost output overvaltage in LP8867C datssheet ,for my use case,the load LED strings voltage variation range from 22.4v to 32v because of ambient temperature change ,the boost…
Part Number: LP8867C-Q1 Hi,
My customer is reviewing LP8867,9 on the LCD backlight.
Based on the reference circuit below, I would like to inquire about the consumption current (MAX) of IC when using LED 2 channels.
input voltage range : 4 - 6V…
Part Number: LP8867C-Q1 Other Parts Discussed in Thread: TPS61194-Q1 Hi team,
I have two questions which are showing as below.
1.
What is (1.2V)VBG difference?
2.
We found that the Vboost_max is different between LP8867C-Q1 and TPS61194-Q1…
Part Number: LP8867C-Q1 Hello, Team,
Generally speaking, does efficiency decrease when the temperature gets high? If so, what is causing this? (thermal characteristics of an internal FET, output capacitors, etc.)
Best, Masaru
Hi Amelie,
For lp8867C-q1, it doesn't have power line FET. But when Vin > VLED + HEADROOM, the output LED will not be on actually since current sink will not open. Why Vin will be greater than the LED voltage in customers' application.

I cannot find Tape and Reel Information for LP8867 in datasheet.
could you tell me where I can find?
Hi Loren,
NT1 is no component to mount but the central star ground connection between GND and PGND. The EVM follows with this star ground connection the layout recommendation given in the datasheet of LP8867C-Q1:
