Part Number: LP8866S-Q1 Hi team,
One question here. Can we read LP8866S's internal temperature by GUI?
I only found thermal shutdown interrupt enable and Thermal shutdown fault status but not actual temperature. Just would like to double check. thanks…
Part Number: LP8866S-Q1 Hi all
I would like to know what is the constant frequency for internal PWM signal that used in this LED Driver (LP8866S-Q1), is there any setting parameter or specification?
Thank you
Part Number: LP8866S-Q1 Hi team,
I have some question here about PWM DIMMING RESOLUTION.
1. We use 124kohms R_PWM_FSET(10bits) then software's brightness set at 16bits(hear from my customer software team). the Vout will high to 27V output at low brightness…
Part Number: LP8866-Q1 Dear TI expert,
We are using the LP8866-Q1 as the backlight driver IC for the screen, which consists of 4 strings of LEDs, each string containing 6 LEDs. We have built the circuit using a boost topology. In the worst-case scenario…
Part Number: LP8866-Q1 Hello Expert,
Our customer is considering to use this device without I2C control.
For this condition, we cannot use following function.
Confirming detailed fault
Using Dither
Configuring detail of Spread spectrum
Is there any…
Hi Team
1.Is the PWM resolution specification up to 0.0001%? Is there any supporting evidence in the specification?
2.Can the backlight be adjusted to 0.1%? s there any supporting evidence in the specification?

Hello Team,
Is there LP8866S-Q1 TINA model available so that we can use the simulation to check PWM waveform and other functions? thanks.
BR,

Part Number: LP8866S-Q1 Hi team,
Very appreciate your support before.
my customer would like to check the PWM_FSET's setting is correct as result that they have tested the OUT pin as below picture test point.
and get the result as below scope waveform…
Part Number: LP8866-Q1 Hi team,
Thanks for your support always!!
I have a quick question here that since LP8866 don't have functional safety in datasheet but have FIT and FMD document. Does it mean this device don't have functional safety but can work…
Part Number: LP8866-Q1 Hi,
In phase-shift PWM mode , all current active channels are turned on and off with a constant delay. In direct PWM mode, all active channels are turned on and off and are synchronized with the input PWM signal.
What is the purpose…
