Part Number: LP8864S-Q1 Tool/software: LP8864 application circuit is as below, it is used as power supply for TFT panel backlight. When LP8864 EN pin is offered 3.3V, 948_VDD_BL_20.58V output 19.6V. But if PWM pin has 305Hz pwm signal input, the backlight…
Part Number: LP8864-Q1 Tool/software: Hello support team,
We are now designing the schematic of LP8864, and we have a problem about the setting of Vboost.
Why should be set the max and min for VBoost?
If we set the R1=680K, and R2=42.2K, the VBoost_Max…

Part Number: LP8864S-Q1 Tool/software: I shorted the LED output while testing the fault interrupt, triggering the LED internal short Status.The corresponding exception 0x484 was read from register 0x12, but after I removed the short circuit and wrote…
Part Number: LP8864-Q1 Tool/software: Hello Zhiqian,
Good day!
When customers perform PWM modulation on the LP8864, the output of the LED_C1/C2/C3 is a gradient buffering process.
对LP8864 进行 PWM 调制时, LED_C1/C2/C3 的输出是一个渐变缓冲过程。
Can they change the register…
