LM2576 Series Buck Regulator Design Procedure
To further simplify the buck regulator design procedure, National Semiconductor is making available computer design software to
be used with the SIMPLE SWITCHER line of switching regulators. Switchers Made Simple (Version 3.3) is available on a (3
diskette for IBM compatible computers from a National Semiconductor sales office in your area.
