Original poster: "David Trimmell" <humanb-at-chaoticuniverse-dot-com> Hi, I was wondering if the SSTC gurus had a good source for the UCC37321(&)2 driver chips? Digikey is pretty pricy. I blew several this last weekend and am in the market... Also, is there another more robust chip that includes an "enable"? Or are other was being used to pulse the ISSTC's? Regards, David Trimmell
