N64 Portable Problem (Please Help)

adamsoileau1
adamsoileau1 over 8 years ago

I am working on N64 portable right now, and like Ben Heck, I am having problems. I rewired the cartridge slot, and it worked great. Then I started to wire the batteries to the N64, and I had problems. On many N64 portables on Instrucatables, they use a Texas Instruments WAS PTH12050 chip, to bump the 7.4 - 12 volts from the batteries to 3.3 for the N64, (because the N64 needs 3.3 volts and 7.4-12 volts). I am using 4 18650 batteries, in parallel and series. So around 7.4 volts with double the amps. It ended up being about 8.4 volts, but when I wired it to the power converter, the output, instead of being 3 volts was 0.5 volts. (This does include the 100 uF capacitor and the 2k resistor that the pages required). This did not work, so then I tried to wire the batteries directly to the board, and 3 volts from another source. This still did not work, but the indicator light was on. I did make sure that the N64 worked with the usual connector, and it worked off the wall. Any tips? I have been stumped on this for a few weeks. I included the wire diagram I used, the circuit I wired, and the link to the page. Any help would be useful.

    1. Input needs to be >10.8V

    2.pin 2 (Track signal) of module needs to be connected to Vi+.

    One more thing. The picture wasn't clear enough for me to be sure but I think your resistor is a Brown- Black- Red  ( 1K ).

    Hi Adam,

    Give us a little wider angle shot of the hookup. It was too out of focus to see much. If you are applying the correct voltage to the buck converter and have the correct polarity it should work unless it is damaged. Put you meter's negative probe on the negative input and take measurements of the input voltage and then the output voltage. One problem may be that the WAS PTH12050 requires an input voltage of 12 volts. 8.4 volts may not be enough to make it work. Here is a link to the Data Sheet.
