Re: Antec Smart Power SP-350 5VSB mod using VIPer 22A pwm chip
I had been wondering why you went to the Viper22A as opposed to the DM311. I had been thinking it was because the Viper22A could handle more power than the DM311, I have not had a chance to read all the threads you have made yet. I did not realize how different the 27 and 22A were until yesterday. I think I was seeing what I wanted to see and not what was actually on the datasheet. I also want to take this opportunity to again futilely complain about the difficulty in comparing the two datasheets.
It is good to know about the VDD, I was trying to see what voltages the 22A had on it when before I decided to have fireworks show instead. Do you know how high the voltage will go under a heavy load? I will rework the Viper27 board and make one for the SOIC-8 Viper22A. It is just as easy to etch multiple different boards as it is a bunch of the same type. I will just have to order some of the SOIC-8 Viper22A's......
