Where can I find information about the LM5000 series of high voltage switching regulators?
General information about the LM5000 series of high voltage switching regulators can be found at http://www.national.com/appinfo/power/hv.html . The LM5000 high-voltage boost/flyback converter and the LM5007 high-voltage buck converter are supported in the online design tools of the Power WEBENCH. Further information and Mathcad files for the LM5000 flyback application are available at http://www.national.com/appinfo/power/lm5000.cgi, which also includes information about the LM5030 push-pull and LM5041 cascaded power converter applications. Also, refer to Application Brief 126, “High voltage, single chip DC/DC regulator optimized for flyback, boost, or forward power converter applications, ” featuring the LM5000.
