DESIGN CONSIDERATIONS  
Figure 19. Basic Circuit for Fixed Output Voltage Applications.  
Figure 20. Basic Circuit for Adjustable Output Voltage Applications  
Power supply design using the LM2676 is greatly simplified by using recommended external components. A wide  
range of inductors, capacitors and Schottky diodes from several manufacturers have been evaluated for use in  
designs that cover the full range of capabilities (input voltage, output voltage and load current) of the LM2676. A  
simple design procedure using nomographs and component tables provided in this data sheet leads to a working  
design with very little effort. Alternatively, the design software, LM267X Made Simple (version 6.0), can also be  
used to provide instant component selection, circuit performance calculations for evaluation, a bill of materials  
component list and a circuit schematic.  
The individual components from the various manufacturers called out for use are still just a small sample of the  
vast array of components available in the industry. While these components are recommended, they are not  
exclusively the only components for use in a design. After a close comparison of component specifications,  
equivalent devices from other manufacturers could be substituted for use in an application.  
Important considerations for each external component and an explanation of how the nomographs and selection  
tables were developed follows.
