LM3475EVAL
概覽
The LM3475 evaluation board is provided as a tool for developing DC/DC converters based on the LM3475 IC. As shown in Figure 1, the evaluation board is configured to provide an output of 2.5V at up to 2A from an input up to 10V. The corresponding bill of material is given in Table 1. Typical efficiencies are shown in Figure 2 and Figure 3. Figure 4 and Figure 5 show the board layout.
