I think that there is a lot of interest in the stepdown converter.
I have purchased some parts to put together a converter using the Maxim 724 chip. Did you use that chip? What is your output voltage (there has been some question as to what the appropriate output voltage is)? What did you use for the R1 and R2 to get that output voltage? Also, how about the capacitor and inductor selection?
When using a 12VDC to 110VAC converter with the webplayer power supply I get lots of interference when playing MP3's in the car. What is your experience with your system in the car? Is your converter adequately filtered to avoid this problem?
What amperage output does your setup allow? I have a CdRom, HardDrive, Not overclocked, and have left the modem in place so there is a fair amount of current needed.
How has your overclock experience been? Did it make the processor flakeir that usual? Did you try any of the higher than 233 setups? Is the improvement in performance noticeable / worth it? If I overclock I guess that will require a fan and added current draw.
Would you be willing to post your converter circuit diagram and parts list?
Thanks in advance for your reply.
