I would like to seek clarification regarding Table 6‑9 (Fault and Protection Schemes) in the datasheet…
Part Number: LP8864S-Q1 Other Parts Discussed in Thread: LP8864-Q1 Hello,
We are using the LP8864S-Q1 in a display backlight application with the following configuration:
Input voltage: 3.3 V
Display backlight: 2 strings × 7 LEDs
LED current…
Part Number: LP8864S-Q1 LP8864S-Q1 LED-DRIVER
Backlinght typical current is 300mA, voltage 8.4(Min)~9.6(Tpy)~10.5(Max)
Now IIC no feedback, to power on the backlight
SCH below, if have issue about SCH.
Also we need the config about open close…
Part Number: LP8864S-Q1 Dear team,
LP8864S-Q1 is used as a backlight driver application. Could you please help review the schematic diagram? As it is not convenient to disclose, can we send it by email?
Part Number: LP8864-Q1 Hello TI expert:
currently i am using LP8864 in my developping project
The input votlage of LP8864 is 16V, The output voltage of LED is about 27V
Then my customer asked us should pass the test:
When runing, input voltage…
Part Number: LP8864-Q1 Tool/software: Hi,
We connected a TFT display with LP8864-Q1 in sepic mode the current set 270mA, and both the MOSFET and the inductor are heating up.
When the switching frequency is set to 500 kHz, the MOSFET(TQM130NB06CR)…

Hi TI team,
could we please do a schematic review of our design around boost LED driver - LP8864-Q1? Could you please send me a private message so I can share the design there, not to share it publicly because of confidentiality…
Part Number: LP8864-Q1 Hi team,
Normally the working condition is input 16V , output 27V,
Once Vin short to 32V, the boost topology will be lost function, 32V will directly lead to LED side, Then in this case, how about the working mode of LP8864…
Part Number: LP8864S-Q1 Tool/software: The LP8864 chip is not connected to a string of lights. After testing the diode, the voltage is 43V. What's going on? After connecting the string of lights, it doesn't light up normally. Is it because the chip is…
Hi Ping Wu,
ping Wu said: so why still recommend use lower inductor? According to the normal boost calculator , the recommend inductor is close to 60uH.
Anyway, after team decision, use 33uH. How about your comments?
The device is with internal…
