Hi Oscar,

I am attaching it now.

Since our project is highly confidential automotive product, i cant send you the full schematics, i am attaching the power section only.

Hi Arjun,

Schematic generally looks fine, but a few comments from me.

I think 470pF for the soft-start cap may have too small of a startup time. You may try it, but I would usually go for something around

I think you may try to add a placeholder for a small high-frequency filtering cap at the output to allow for better response time, but it is up to you.

Regards,

Richard

Hi Richard,

What value should be used instead of 470pF. i am not seeing any values in your reply

Also do you have any suggestions for 'small high-frequency filtering cap' you mentioned. just value will be enough.

Regards,

Arjun

Hi Arjun,

Sorry, I meant to write something around 10-20nF.

High-frequency filtering cap can be something like 1uF.

Regards,

Richard
