I figured someone here as more expertise on stepping down voltage.....here is the deal.
I bought my kid a clock radio. It didn't come with an adapter. The clock it negative tipped, and is rated for 4.5v. I found a 6v 800ma adapter I can basterdize. I would think that 6v (and I may be wrong) would be too much, and need to step it down closer to 4.5v
I know the UA5 adapter I made will work anywhere between 9v and 12v
What is the simplest way step the voltage down to 4.5v
Many thanks in advance
