Part Number: LP8866-Q1 Hi All,
I have a question about LP8866.
Depending on the timing of the input PWM signal, the waveform will be as follows. The output voltage rises. It disappears by shortening the Low period of PWM.
It seems that the soft start…
Part Number: LP8866-Q1 Hi All,
I have a question about LP8866-Q1.
How do you set the values for the resistor Rfb4 and the capacitor Ccomp, referring to the schematics on the "Figure 8-5" ? There was no specific value or calculation method in…
Part Number: LP8866-Q1 Hi All,
I have a question about LP8866-Q1.
Is it possible to control the dimming of the LEDs from OUT1 to OUT6 individually? For example, OUT1 is 50% Duty dimming, OUT1 is 10% Duty dimming.
Also, please tell me how to adjust OUTx…

Hi Team,
There are two dimming modes in the 8863 data sheet. Is pure PWM dimming (8863) equivalent to Phase- shift or Direct PWM mode in 8866?
Also about the PWM Input in the picture below:
If BRT_MODE is set to 2h, can customer…
Part Number: LP8866-Q1 Hi,
In emergency situations, the backlight will flash when Vin is 8V, We use X-Ray to confirm that the status of PCB printing is OK, and the boot sequence Vin, VDD, EN are normal!
It is found that the SD Pin that controls the MOSFET…
Part Number: LP8866-Q1 Hi All,
I have a question about LP8866-Q1.
If you set Direct PWM Mode, I think PWM_FSET will be disabled. In that case, what should the resistance value of PWM_FSET be set to? Is it GND? Or is it an arbitrary resistance value?
Best…
Part Number: LP8866-Q1 Hi team
I would like to ask a question that when we detect a certain FAULT happened from LED_STATUS, could we disable the fault channel individually? Since I see if we set the LED_SET resistor for 6 channels fixed, the number of…
Part Number: LP8866S-Q1 Hi Bro,
Software issue
After pulling low the EN PIN of LP8866S and turning off the output ! Then Pull HIGH again and it won’t turn on again!
LP8863 used the same program before but it was fine, what will cause the result, …
