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: 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?

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 Hi experts,
My customer have three questions about current during boost start as in datasheet Fig.21.
1. How to estimate the maximum current during boost start? They want to know when Vin=8V & 16V.
2. Does rush current flow…
