DC-DC Converters - Sources?
Moderator:Moderators
Where can I get a dc-dc converter for my N64p? Are there any stores/businesses other than on-line?
--------note that it requires at least 9v on the input side. (and is most efficient at that vvoltage too). if you cant make a 10 volt battery pack, then look for another product. they probably have it. they just might not offer free samples for it.
Which one should I get then for a 7.2v battery? Better yet, could someone link me to where I get the free sample for a 7.2v battery?
Marshall, i got this converter today in the mail from TI:

I plan to use a 7.4v battery with it. Would this work?
Also, if it would work, does this converter bump the voltage down to 3.3v or does it boost it to 12v?

Looking at the datasheet, you're going to need a bunch of extra parts to use that (not to mention soldering to the tiny SMT package.)
The one that I (and some other people) are using is here.

It's dead simple to use.

Yeah, the free TI converters are very nice for first-timers or anyone else. Im not sure if they are extremely efficient under load, but they work well.
Also, they are so easy to hook up and use. All you do is connect an input line (from your battery. 7.4V would work) connect a ground (goes back to the ground of the battery) and an output line (outputs 3.3V from the converter). 3 wires and its all hooked up and ready to go.
Edit: Sorry! forgot about the capacitor again...You also need a 100uF electrolytic capacitor on the output of the converter

And an electolytic 100 uf capacitor on the output. You need that! And make sure your battery ground is connected to the N64 ground.Neildo_64 wrote:Yeah, the free TI converters are very nice for first-timers or anyone else. Im not sure if they are extremely efficient under load, but they work well.

I can't be more blunt than that. If you won't believe me then I'm afraid I can't help you there.
no...Im asking which model I should get for the 7.2v...theres like 5 different models.
