GB For Salas SSLV1.3 Ultra-BIB

[tome]

Hi Tea-Bag
Can you put me on your list for 2 Ultra-BiB boards.
Thanks

Hi,
Just signed up for 2 boards - to Ireland (REP.)

Hello,

Signed up for two sets of each, not sure if it was saved on the list.

Thanks for this.

Regards,
Ted

I signed up for a PCB and three Minikits. Cool stuff. I look forward to try it out with my Soekris DAC... Could be quite a bit better than the LM317 solution I currently use. Fedde

Anyone who needs a to operaate as a 5V reg, and so therefore a J3 of < 7.5ma let me know. I have some selected PF5102 for this effort. Please add to the notes section of the spreadsheet. Thanks.

Thanks for making that happen for me! I grabbed enough Ultra-BIB's to upgrade all the shunt-regs in my Red Baron DAC project. This should really make it sweet!

I made the payment and also updated the Google sheet with the notes for a set of Ultra BiB boards + 2 +ve mini kits + 1 -ve mini kit. Just to clarify that the PayPal invoice had it mentioned as "1 +ve mini kit and 2 -ve mini kits".

Thanks

I would like to get 1 pcs Salas Ultra BiB
please confirm that I can use for + 5 Vdc and - 5 Vdc

Boards and mini kit

Hi Salas,

Signed up for two boards, 4 pos kits and 2 negative kits.
Pl advise for payment.

Cheers!

Hi Tea-Bag,
Signed up for 2 Ultra-BiB boards to Germany. If you had some spare PF5102 < 7.5mA for 5V application, I would buy six of them too.

Please send me the Paypal invoice.

Best regards,
Trung

Quick question regarding R1. have you the formula for calculating the value please?

 

[Tea-Bag]

Quick question regarding R1. have you the formula for calculating the value please?

Here is some words on it from Salas.

"Lets try some numbers:

Say for typical R1 values you use 2.2R in the positive and 3.9R in the negative. The formula* is CCSmA=600/R1. Thus 600/2.2=272mA & 600/3.9=154mA.

You said the Soekris current load spec is 180mA for the positive & 60mA for the negative. Because spare current in the reg is CCS-load then 272-180=92mA & 154-60=94mA. Balanced spare current on both rails is achieved, both M2s will dissipate the same. Zo and other characteristics will also be given a chance to be nearer in both sections.

The drawn current total should be CCSpos+CCSneg=272+154=426mA i.e. a very near total to my 200+200=400mA 7.6W pulling as measured test build. Should indeed be around 8W when set for Soekris because of the +26mA total in the described setting than the measured example's.

*When looking for R1 numbers through a CCS setting target the formula can be turned into R1=600/CCSmA. Say you go for 150mA setting, then 600/150=4R so 3.9R is the nearest. Its the one I just used for setting the UltraBiB's negative section current limit in the Soekris example."
