Part Number: LP8860-Q1 Tool/software: Customer seen boost voltage difference had been verified on TI EVM and no difference seen for return units and good unit.
It is observed impedance and boost waveforms are anomaly after re-solder the TI parts on the…
Part Number: LP8860-Q1 Hello,
LP8860-Q1 LED driver is used as a backlight driver in one of our applications.
On a test station we have to verify ICs via I2C. The only device related data is the ID, stored in the following register (0x12):
Read value…
Part Number: LP8860-Q1 Tool/software: Hello TI,
We are working with the lp8860-q1 right now and need to know about one thing, can we control the led brightness using I2C without giving PWM signal input??
Our primary requirement is to control the brightness…
Part Number: LP8860-Q1 The panel datasheet indicates that the LED voltage VF max. is 60V and we will deside using the LP8860-Q1 for the solution.
However, the simplified schematic of LP8860-Q1 specifies voltage of up to 48V. How can we design the 60V of…
Part Number: LP8860-Q1 Hi team,
1. When PL_SD_LEVEL[1:0]=10, is the VSENSE Voltage a fixed value? If so, what is the fixed value? 2. When PL_SD_LEVEL[1:0]=11, is the VSENSE Voltage a fixed value? If so, what is the fixed value? 3. When BOOST_IMAX_SEL…
Part Number: LP8864S-Q1 Other Parts Discussed in Thread: LP8860-Q1 Hi team,
Are there calculator tools for LP8860-Q1 and LP8864S-Q1 that can be provided to customers for design assistance? If so please help send it to me.
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…
