Part Number: LP8866-Q1 Tool/software: Hi , Please let me know how to calculate maximum power dissipation of this IC LP8866. All 6 channel led string we are using. Total current 6 strings =780mA per string max 130mA
Part Number: LP8866S-Q1 Tool/software: Hi team,
for this function, how can we implement this smooth function? can you share more details about this? we just replace the brightness function from the liner function to a smoother function, is this right…
Part Number: LP8866S-Q1 Tool/software: q1.datasheet page 1 ,12 bit analog dimming What is the Dimming ratio? Is this the 2^11?
q2.Is there a formula for the relationship between dimming rate and PWM frequency in section 7.3.8.3 LED Dimmig Frequency?…
Part Number: LP8866S-Q1 Tool/software: Hi team,
My customer want to use the Lp8866s Pwm pin to control the brightness instead of using the IIC control, will PWM dimming ratio the same?
For my side , i think if only use the PWM pin to control the brightness…
Part Number: LP8866-Q1 Tool/software: Hello, I need to consult the following questions about LP8866: 1, there are 19 LED, 2 series (10+9), each series needs 500mA current, as shown below the connection mode can work normally? Is there a problem?
2. If…
Part Number: LP8866-Q1 Hello !
For our backlight driver we are using LP8866QDCPRQ1 with the minimal design solution . We are driving a display with 6 strings x 11 leds per string . The system works fine at room temperature. When we are testing @-40C, we…
Part Number: LP8866S-Q1 Tool/software: Dear expert,
Below is PCN for LP8866s which mentioned rev C datasheet. But ti.com only has rev B datasheet.
When can I find rev C datasheet? Thanks

Part Number: LP8866-Q1 Tool/software: Zhiqian,
Customer LP8866 is already in mass production. But randomly many LP8866 report BSTOVPL alarm with INT pull low.
You can see from below capture. VIN is up before VDD. Around 7s after boost is up, INT is…
Part Number: LP8866S-Q1 Tool/software: Hi Team
I have a question about 8866s. I want to confirm that this RC has the snubber function? Does it have other functions besides this?
Thanks,
Boyan
Part Number: LP8866S-Q1 Tool/software: If my customer wants to use the maximum 48V input voltage allowed, can they program the OVP to be higher than 48V? How would they do this? It's not clear what the limit is for the low & high threshold for OVP.…
