Part Number: LP8867-Q1 Tool/software: Hi Team,
It seems that there are 2 different package type in LP8867-Q1 datasheet.
=> PWP0020W + PWP0020N
If we want to use the LP8867QPWPRQ1, which package type we should use?
Thank you.
Part Number: LP8867-Q1 Tool/software: Hello, I was doing some calculations for and there are instances where the input voltage exceeds the boost voltage. Lets say that the input voltage is 36V and the boost voltage is 29V. What happens then?. I have an…
Part Number: LP8867-Q1 Tool/software: HI team,
My customer HIWAY is debugging LP8867-Q1.
Our current issue is that after VIN and EN powered on, FAULT goes high, but when PWM is applied, fault goes low.
The attachment is Schematic, please help review…
Part Number: LP8867-Q1 Tool/software: Hi Team,
What value should use Injection resister and injection voltage to measure the phase margin?
Do you have any document for the measurement the loop of the LED driver?
Best,

Part Number: LP8867-Q1 Tool/software: Hi Team,
Customer is using LP88670-Q1 in following conditions.
VIN:6V
Vout:33V
Iout:400mA
However the efficiency is not good and There is no margin of the boost current capability. Do we have any recommended…
Hi Christian,
It seems to me the requirements should apply to all the ICs on the PCB, not particular for LP8867-Q1. So I ask what other IC's spec here. I think nothing particular for LP8867-Q1.

Hi Tyrique,
As I first asked,
Gracie Guo said: Did you try ABA swap to find if it's IC failure?
Did you change to other chips? Is it production or design phase failure? If so, it's IC failure and you may request QEM.
BR, Gracie
Part Number: LP8867-Q1 Tool/software: Hi team,
My customer is using LP8867-Q1 for their project and they want us to help them to review the schematic, and they have a problem about the configuration of VDDIO so I'm looking for your help.
I have attached…
