Hi,
I am using the LP8867-Q1, but not enough margin is measured when measuring the phase/gain margin.
To secure phase/gain margin, measurement data according to snubber circuit and feedforward capacitor are attached.
This is the area marked with a red box, and please help if you have any measures to secure the phase/gain margin.
And please answer the questions below.
1. Doesn't it matter if the capacity value of the feedforward capacitor is set to 4.7pF or 6.8pF? Is there any possibility that other side-effects may occur?
2. If the snubber circuit is not applied, the phase/gain margin is insufficient. Is there a way to secure phase/gain margin without applying snubber circuit?
