... LM2673S-5_EVAL LM2679S-5_EVAL evaluation boards. General Description Many of our boards are intended to provide the user with de- vice characterization and layout optimization data. The LM267x evaluation board was intended to allow the user to experiment with a variety of circuit topologies and compo- nents, and therefore not optimized for size ...
