Release Ps2 voltage regulator board

[Customledmods]

thanks to my good friend @Mister M for designing this regulator board for the advance ps2 trim. It’s been about 2 weeks since I put my board together and tested it, I’m now ready to share the files and bom with everyone who may want to use them.

Here are the Digi-Key parts list. Everything seems to be in stock at the moment.

R6 - is 953k ohm resistor. In the download bom it says 95.3k

Can you run this with a 1s battery pack?

I tested it with a usb c 3amp power bank, it worked but my power bank kept turning off. I’m currently testing another power bank module.

UPDATE

Bought a new power bank thanks to @Senor Avocado for providing link) this one doesn’t turn off and powers the unit off 1 USB port.

I am curious on what power bank you're using. Aside from that, this is amazing! Great job dude!

I have been trying to buy lp2992 ic-s are there any alternatives?

Check these out I think they’re the same and in stock.

I did an update to the BOM, so everything can be sourced off LCSC with no out of stock Parts. Maybe this is useful for someone. The fixed Resistor value and it's lcsc part is updated. The only downside is that some Parts aren't from the same manufacturer anymore, but the tolerances are the same. Prices are updated for today and the parts will end up to cost around $15-$20
The BOM can be placed directly in the lcsc BOM tool, the Quantity is suitable for one Board.
Be aware that some parts have a minimum quantity to order.

Hey great job this will be useful

Hey, I have a Question about the Board. As I just saw a Video about how Inductors work, I am now a little concerned about something called "flyback". On disconnection of the power source it can lead to very high voltage spikes. I do hope this isn't a problem in this particular design as I don't see any diode.

I don't know about sharing links here, I will look up the rules Tomorrow and share the yt link if possible.

It hasn't been a problem for any regulator board designed so far, but if you're concerned about flyback you can integrate a clamp diode to prevent it

Alright, thank you for the reply, I guess since you answered this, I will not unnecessarily share the Video here.

Ok I built one of these and the voltages are correct for the 2.5v and 1.25v rails, but the other 3 are all wrong. The readings I get are as follows:

5v pad - 0.06v
3.5v pad - 1.2, then drops to 0.82ish
1.25v pad - 0.78

The linear regs are all correct.

Any idea what I've done wrong?

Check for shorts on TLV62130RGTR. Can you upload some pictures

Ah I'll bet I know the problem. Here's a picture of one of my unpopulated boards I ordered. I figured those pads were supposed to be bridged like they are.

 

[Customledmods]

Yea that might be the problem mine weren’t like that when I ordered them. Do you have another board that they’re not shorted ?

Unfortunately they all look identical. Awell, I'll call this one soldering practice and order some others.
