From: Joaquim Carvalho <jdc_at_x64.com>
Date: 14 Jan 2003 12:57:35 +0000 The first I'll do when I get the jukebox is a voltage doubler to charge the batteries from the USB cable. All easily available ingredients: 2 or 3 MAX660 voltage doublers (200 or 300mA output current) http://www.national.com/ds/MA/MAX660.pdf 88% efficiency 5.5V max 100mA each SO-8 package 3 or 4 150uF smd tantalum capacitors Any other suggestions?
