Salas/others,
Due to space limitations I will have to design my own board for 2 SSHV2's.

- Are there any layout recommendations? (components that should be as close as possible to one another, components that should be furthest apart?)

Thanks!

The input CCS is critical for compactness primarily. In the GB PCB it works with 100 Ohm gate resistors which is generally not that common, people use >=1K to damp the depletion semis, alas if you need to, it cuts PSRR dB max spec in the highs.

Hey Salas,

Whereabouts is the GB for the PCB please?

Thanks,

D

[Salas]

At the GB forums.

Well that was a dummy question on my part then.....

Thanks Salas.

Forgive my lack of knowledge but that four wires out looks complicated to me. Usually I just have to deal with "in, out and adjust"...

I want to use the SSHV2 with my 12B4 preamp (Salas version).

A bit more information would be welcome.

Thanks.

You have two pairs of wires that connect at the load.. Sense and Force (remote sensing).

So both S and F are going to your plus side while both SO and FO go to the ground side. You should also download the build guide at post no. 2704.

Connect each S to the respective F at the regulator.
Now you have a two wire connection to your load.

It's that easy if you want it to be that easy.

I have. Those Sense and Force connections are needed to get the regulator performing well. Thanks.
