Power Supply Design

Please click here to visit the Comdel websitePower supply design, as with most realms of circuit design, is largely pre-packaged in the form of an integrated circuit (with a handful of capacitors and maybe an inductor) or a complete module. Of those applications where a power supply needs to be designed from scratch, there is still a large cache of off-the-shelf components that makes integrations a relatively simple matter, once you know what your specifications are. The resources listed here should help to get you through any power supply design scenario. If you cannot find what you need, call one of the companies and ask for some guidance. Most are willing to give some help.
