Part Number: LP8860-Q1 I have some questions, Pls help to reply.
We use I2C to set the register, and the boost frequency is 303K, not use the PLL.
During the EMC test(RE/CE), we find the internal frequency 10M signal can out of the head unit, and we…
Part Number: LP8860-Q1 Hi TI Team
We changed the LP8860 Charge pump clock frequency from 833KHz to 417KHz. Will changing this frequency affect EMC? No information about Charge pump clock frequency was obtained from Spec.
Thanks
Part Number: LP8860-Q1 Is there a default value for the 0x02 and 0x03 registers of lp8860?
We have found that there is a problem with the same brightness, but the main screen is darker than the secondary screen. Upon checking the backlight chip register…
Part Number: LP8860-Q1 Hello,
due to insufficient information in the data sheet, I have questions about setting the LED current on the LP8860. In our application LP8860 is driving 4 LED chains in display mode. The current should be limited by external…
Part Number: LP8860-Q1 Hello,
I would like to ask you a question about LP8860-Q1. The figure below shows the waveform at startup. Depending on the device, some devices maintain a constant output voltage during the 50ms BOOST START period, while others reduce…
Part Number: LP8860-Q1 Hi team,
As shown in the figure is the description of the EEPROM chapter of LP8860. What is the logical relationship between 00h~1Ah and 60h~78h? For example: The customer sets the current value of each channel. 0x60, 0x61, 0x02…

About LP8860-Q1 pwm PIN Settings
In datasheet
BRT_MODE original value is 10, directly through the IIC to write 00, read later, found 10. It's not changed to.
Excuse me, do not burn EEPROM, How to setting PWM pin.
Part Number: LP8860-Q1 Hi,
The register LED_CURRENT is calculated including the PWM?
If not, it means the value of the register is exactly the current that configured in register DRV_LED_CURRENT_SCALE?
Part Number: LP8860-Q1 Hello TI expert,
We are using TI LP8860 backlight chip, in our design we make the Cathnod of the 3x LED strings shorted together in display side as below picture.
Check the LP8860 datasheet seems connecting the LEDs Cathnod…
Part Number: LP8860-Q1 hello experts:
at my use case , the led panel let the backlight LED cathode connect together and the LED cathode connect the LP8860 three leans , i want to know if there any issue with this use case ?
