1 Introduction

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

To aid in the design and evaluation of DC/DC buck converters based on the LM3475 controller, the LM3475 evaluation board can be easily re-configured for different output voltages.
