SNOSCY4E March 2015 – October 2018 LMG5200
When designing a synchronous buck converter application that incorporates the LMG5200 power stage, some design considerations must be evaluated first to make the most appropriate selection. Among these considerations are the input voltages, passive components, operating frequency, and controller selection.Table 4 shows some sample values for a typical application. See Power Supply Recommendations, Layout, and Power Dissipation for other key design considerations for the LMG5200.
