It's not necessary, but I'm not going to tell you it's a bad idea. I know of a few names on this list who have used PICs in real, working, SMPS designs without doing complex analysis. -- Martin K. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
