Part Number: LP8866S-Q1
Hi All,
I have some question regarding LED Driver LP8866S-Q1
1. In LP8866S-Q1 Datasheet page 26, there is a diagram for Brightness Path Diagram
If we set the method for the output current is "PWM" how can we ensure the output…
Part Number: LP8866-Q1 We are using LP8866-Q1 in SEPIC mode and to calculate the Mosfet dissipation, we are in need of Gate drive current from LP8866-Q1. In datasheet i am not able to find that. Please someone help with this.
Part Number: LP8866-Q1 Hi team,
thanks for your support before.
I have a question here that since my customer will need to pass EMI of LP8866-Q1.
the result at below:
Switching Frequency 500kHz with 22uH can pass EMI the closest pass value is under 3dB…
Part Number: LP8866-Q1 Hi Expert team,
I want to use a coupled inductor in SEPIC configuration of LP8866-Q1 backlight driver. In datasheet or on e2e I did not find any related topic to understand the requirement for this. is there anything I need to take…
Part Number: LP8866-Q1 Hi Expert,
May I know the 32000:1 dimming ratio using 152HZ PWM frequency is for direct PWM dimming mode or other? Does 32000:1 dimming ratio can be achieved if using phase shift PWM mode?
Thanks!

Part Number: LP8866-Q1 Hi team,
Do we have technical reference for LP8866?
Since my customer is asking that does the value of PWM_INPUT_DIAGNOSTICS Register (Offset = 16h) and PWM_OUTPUT_DIAGNOSTICS Register (Offset = 18h) generally be same?
I would need to…
Part Number: LP8866-Q1 Hello,
In Hybrid mode, is the PMW phase shifted? Or phase shift is active only in Phase-shift PWM mode?
Thank you.

Part Number: LP8866-Q1 Hello,
in our design we are using the following LED driver and currently facing some RI problems on the I2C Bus channel since it's shared with an ambient light sensor from TI as well, in order to fix those problems, we had add some…
Part Number: LP8866S-Q1 Other Parts Discussed in Thread: LP8866-Q1 Hi all,
In LP8866-Q1 BOOST LED Driver Design Tool, there is calculated parameter for VBOOST_OVP_LOW_Init
But refer to the attachment equation, for that part using this equation : VBO…
Part Number: LP8866S-Q1 Hi all.
I do the calculation for BOOST wit considering Fedback Resistor (3 Resistor) and here the result:
and I also do the measurement using Oscilloscope
I would like to know is my measurement result is normal? and for VBOOST_UVP_HIGH…
