PSP charging circuit
I need a little help with this
Recently I got a v1.5 PSP that was faulty of ebay for a test PSP as I already have some good v1.5ís that I didnít wonít to be bricked.
The mem card and wifi on the board wasnít working on the PSP this was down to a problem on the connector that connects the main board to the mem and wifi boards.
Now the only problem I have now is the charging circuit on the PSP, I have everything else working on the unit but if I plug in the charger the PSP will stop working till I unplug the changer. It will just stop where it is like I paused it.
And no matter what I try I canít get the changer working.
So we all know the changer on the PSP is 5v and the battery is 3.6v now I was thinking of just hocking the + on the power to the + on the battery port but will this overload the PSP?
Or will the PSP be ok with 5v running to the battery?
When the PSP has the changer plugged in dose it supply 5v to the battery or dose it step-down the voltage?
If so how easy would it be to build my own step-down circuit? Iím thinking of some resisters.
I know itís not too bad as itís almost fully working but I like to get everything working on something Iím working on
So any help would be great!
If you apply 5v to that battery it will be gone. I dont think a normal step down circuit will work because this is a lipo battery and needs to know when to peak. If it just keeps getting power it will blow. You might wanna try to fix the board rather than doing some home inventing.
Hmmmm ok then maybe another way to do this then?
Is there a battery pack that has its own changing port like you use to get back in the gameboy days?
That way bypassing the changer altogether?
Believe me I have tried to get the changer working on this board but it seems that if I get the changer working ether the mem slot will stop working or the wifi, I can never get all 3 working :(
hmm. I know there are no batteries that have external chargers like your talking about. It makes it hard becase it a lipo pack. Go in with a volt-meter and see what is comming out of the battery plugs on the psp side of it while charging.
I'll have a look tonight on one of the other PSP's to see how many volts its supplying when changing.
Iíll post my finding later tonight :)
