Re: 14.4v till 12v till 6v till 3v?

Angående WRT54GS så kan man av bilder på kretskortet se att det är en switchad lösning. Men denna sida borde göra klart vad som fungerar som inspänning till WRT54GS v1.0.
" It is the AC1501-03 from Anachip Corp., an integrated 150kHz step-down switching regulator with thermal and over-current protection. It works with a supply voltage between 4.75V-40.0V and gives a stabilized 3.3V @ 3A.
That means that the lower limit of the supply voltage is about 5V but the upper limit is much less than 40V. That's because the input capacitor is rated at 25V, so I would not suggest running it on more than 20V."
6 V regleras bäst med switchad lösning, t.ex Nationals "simple switcher" på ELFA.
3 V kan väl tas med en linjär regulator.
