Part Number: LP8866-Q1 Hi team,
We found that Recommended Capacitor of VDD& Cpump are different in datasheet between the Table 5-1 and Table 8-7.
If VDD is 5V, should I choose Cvdd = 10 uF & Cpump = 4.7 uF, or Cvdd = 4.7 uF+0.1 uF & Cpump = 10uF?…

Hi All,
I have a question about I2C for LP8866-Q1.
In the standard specification for I2C, it is stated that VIL=0.3VDD(min). (VOL = 0.4V is stated.)
However, LP8866-Q1's VIL = 0.4V(max) is stated. When VIL is as described in…
Part Number: LP8866-Q1 The backlit driver is LP8866, with three outputs and 18 LED beads, each with 6 beads.
Now if the PWM of LP8866 is adjusted to the maximum 100%, the backlight will flash, but it will not flash if you slowly increase it. What is the…

Hi team
The input voltage is 8~18V, and the minimum LED Vf voltage is 3V * 6 = 18V.
Can Boost mode be used in this situation?

Part Number: LP8866S-Q1 Dear expert,
Customer use LP8866s for 4~5V LED.
They want to know whether they can bypass LP8866s boost? Or can they simply use external 4.5V for LED power?
I know we have other LED driver to better meet their requirement but now…
Part Number: LP8866S-Q1 Dear expert,
I want to use LP8866S to support 14 LED in series. 3.3V for each LED. 14*3.3=46.2V
Max boost output of LP8866s is 48V
Is it any risk to support this scenario?
If only support 13 such kind of LED, it should be safe…
Part Number: LP8866-Q1 Other Parts Discussed in Thread: LP8863-Q1 Hi All,
I have a question about the LP8866.
Connect to GND if OUTx of the LP8866 is not used. If you connect to GND, do you connect to LED_GND or PGND?
Best Regards, Ishiwata
Part Number: LP8866-Q1 Hi All,
I have a question about LP8866-Q1. A customer is evaluating the LP8866-Q1. The operating conditions are VIN=26V, VDD=3.3V, VEN=3.3V.
The customer's SCL and SDA input rise time is 350-450nsec, is this a problem? The datasheet…
Part Number: LP8866-Q1 Hi Team
There is a good new that we could DIN LP8866!
Because customer spec is input voltage 8~18V, LED Vf minimum voltage 3V * 6 =18V, so they will use SEPIC topology
Please provide the SEPIC reference schematic and BOM list and…
