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…
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)…
Part Number: LP8864S-Q1 Tool/software: Hi experts,
My customer Chery is using our LP8864S-Q1 on their Automotive display projects, could you please help provide the LP8864S-Q1 calculation tools for customer? Thanks!
Best regards,

Part Number: LP8864-Q1 Tool/software: Hello Ti-Team, We have to design a controllable current source, which has to dim our high-power UV-LED analog.
The current should be regulated with the 12 Bit resolution. Our full scale current is 250mA. We would…
Part Number: LP8864S-Q1 Tool/software: Hi team,
In LP8864S-Q1, there is booster mode and SEPIC mode, what is the difference? Can SEPIC mode work on both booster mode and buck mode?
for example, in my truck project, battery voltage is 24V typical(16V…
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: LP8864S-Q1 Tool/software: Hello team,
I have a question regarding the switching FET used in LP886X(S) circuit.
In LP886X(S) datasheet it recommended to use switching FET with Rdson resistance <20mohm. I want to try a FET with max Rdson…
Part Number: LP8864S-Q1 Tool/software: team, can you please confirm that this device requires an external Vdd and doesnt draw current from the Vin (vsense pins) ?
therefore the shutdown current would exclusively be the Vdd shutdown current. If the device…
