Custom Regulators

[Wadebrody]

Does anyone have any pictures of their custom regulators wired up to their Wii? I've been looking around but all I see is where the voltages are, on the Wii Trimming Guide. And also, do you need the custom 5v regulator or is that just optional? Thanks

I'm quoting this post from SSWiiT topic. You can see all the needed regs wired up. Also you don't need to wire a 5V regulator to the Wii motherboard, but you still need it for USB power and for the fan.

Thanks, this helped a little bit more

So you do or don't have to make a whole new regulator for USB and the fan?

Yeah you still need one

 

[Wadebrody]

Yeah you still need one

Oh, okay. Thanks!

For the 5v regulator, do you need 353 ohm resistors then? I'm just reading off of the PTH08080 pdf

I assume you are using a PTH08080. If that's the case then yes

 

[Wadebrody]

I assume you are using a PTH08080.

On the Portablizing BOM it has PTH08080WAZTs but I hear a lot of people using PTH08080WAHs though. All I could find for differences were that the WAZT was surface mounted and the WAH was through hole. Does it matter which one I use? (sorry for all the questions)

No, it doesn't matter. They are the same thing (except for how they are usually mounted on PCBs)

I know that I just got my PTH08080WAH's yesterday and they are through hole mount, (or supposed to be) but they don't fit any perfboard that I have... the spacing is way off. Anyone else run into this?

As far as I know, most people don't mount their TI regs on perf board. I think most people wire them up and glue them into the case without mounting them to anything else

 

[MiseriesChild]

Weird, I've seen it done both ways but the more research I do it seems that people are using custom breakout boards if they do mount them somewhere. Make's ya wonder why they even put pegs on them if they aren't made to fit into perf board, lol!!

I will take your advice and wire 'em up, test 'em and glue 'em in. Thanks for solving the mystery for me... I couldn't figure out how everyone had been mounting these dang things, lol!!

 

[Shank]

Well, they are made to fit onto OTHER boards, but not perf board specifically. They are made so you can design a circuit board that the pth08080 module can plug right into.

I just ordered mine, and am for the most part clear on using them despite this being my first custom regulator setup. However, on the datasheet for the pth08080wahs I ordered, it says to make sure the capacitors I use have a certain ripple current resistance.
"When VO > 3.4 V, the 100-µF electrolytic
capacitance must be rated for 650-mArms ripple current."

I ordered 100 micro farad capacitors, but I can't seem to find anything about their rated ripple current or how to calculate it. Should I just assume it's okay?

Should be fine. Feel the capacitor after the system has been running for a bit. If it's hot, you may want to replace it, but most likely it will be at most warm or room temperature.

Hi everyone....i am a new user here. I have seen it done both ways but the more research I do it seems that people are using custom breakout boards if they do mount them somewhere. Make's ya wonder why they even put pegs on them if they aren't made to fit into performance board.
